Text of the page (random words):
it does not exist yet the paper airplane browser and editor also support tabs similar to firefox the browser can have several tabs open showing different web sites and pages with some of them being in edit mode the user can jump between tabs to quickly compile information while editing for example or can be co editing several pages at once either alone or with others see the instant messaging section for details on real time collaborative editing autolinking and the tabs work seamlessly together as well as page names are autolinked in the editor while you are typing the user can choose to open the auto linked page into a new browser tab to browse this new page or begin editing it as well this combination of tags and autolinking make working in the editor feel very stream of consciousness and organic the editor also brings to wikis something long missing autosave at regular intervals the editor saves the user s contents as drafts that can be later retrieved if the browser crashes or the user accidentally navigates away never lose your creative work again when a page is saved or created it is stored into the p2p mesh the p2p mesh paper airplane uses a p2p mesh to achieve much of its functionality in a transparent manner so end users do not have to struggle with common administrative tasks peer to peer means that ordinary end users machines are used to co create the network napster did this with sharing music files while skype does it with finding and routing internet voice telephone calls using normal end user machines the upshot is that very affordable networks can be created in a decentralized automatic manner paper airplane uses a p2p mesh to achieve the following functions routing around network blockages such as nats and firewalls a domain name system named disdns for storing dns names and resolving them a presence and communication fabric for instant messaging and virtualized storage using available p2p nodes for saving and replicating web sites the nodes in this p2p network are the paper airplane browsers themselves instant messaging as users are browsing a site they will see other users that are also members of this site in their sidebar this im client is a simple aol instant messenger type client where users can communicate one on one or form simple group conferences to communicate as they browse the site the im sidebar respects the type of site it is attached to such as whether it is super public or private if a site is super public then everyone on the site is shown while a private site reveals private members only a restricted public site would only show those who have joined the site reducing presence clutter in the sidebar and allowing members to focus on each other to work productively while editing a document if another user would also like to edit this document a popup will appear saying that another user is requesting to edit this document if you agree the editor changes into a collaborative editor with the im client located in the sidebar along with the same formatting palletes that were discussed in the section the editor every user is assigned a color and as you edit add and remove content and objects the background color of these sections is different similar to subethaedit every user also gets a differently colored cursor so they can see what the other is editing the combination of shared editing with real time communication is extremely powerful especially since the tools for single and collaborative editing are almost identical the end result is that users can do private and communal editing without learning a new skill set the smart browser tools for navigation in browsers progressed rapidly in the early days of the web until they finally froze at their current state in about 1995 and have remained relatively unchanged this is sad as the brower could standardize and embed many tools for much more sophisticated ways of dealing with web site s especially around collaboration it s time for innovation paper airplane takes this to the next level with the concept of the smart brower where the browser embeds standard navigation controls across the two way web sites it creates this section discusses how the smart browser makes end user s lives easier first paper airplane embeds single signon when a user first starts paper airplane they authenticate themselves against the browser using a signon dialog to unlock a public private keypair that is stored on the local machine this public private keypair is linked to a handle similar to an aol screen name that is globally unique it does not establish that they are a specific person but rather that they have a particular handle then as they navigate to each two way web site the browser authenticates them in the background using these keypairs against the remote site single signon goes hand in hand with a standard way to join and unjoin two way web sites at any site if the site creator made it open a user can press the join button to become a member of this site when this is pressed in the background the browser sends the user s public key to the remote site to be used later for single sign on activities editing and site roles the next standardized interface in the smart browser is a standard way to track site changes which is a panel that appears in the left hand sidebar when selected this panel is created by using an rss stream from the remote site and can track recent site edits using the paper airplane editor or if the remote site is a blog recent updates to a blog or corporate site for example when users go to a new site they won t have to wonder what has changed the recent changes panel makes it easy for them members of sites can also easily manage roles with the members sidebar every page also has a control so that users can tag it with a given topic such as important todo or linux for example then by pressing the navigator section in the sidebar they can view all of the pages in a web site sorted by tag by name and more this navigator makes it possible for users to quickly jump to new adhoc categories created by other users sorted into bottom up categories using the tagging control the navigator also includes other powerful ways to view a web site recently edited which shows recently edited pages and my recent pages which shows your own recently edited or viewed pages so that you can quickly jump back to them the end result is that structure is brought to collaborative sites in a bottom up organic manner rather than through top down controls that quickly become out of date the navigator also exposes a sorting type called by index which takes a bit of explaining but which is very powerful as pages are created and edited an automatic index is created in the background when a user views a site in the navigator by index they will see an automatic index similar to the index in the back of a book or the one in microsoft help defining all the words topics and relations gleaned from the site itself most importantly if your site members have used smart templates to create pages that have simple semantic information in them then we now have higher level metadata to hook our index on to the index can be an extremely powerful way for users to look into the back of the book in a sense and jump right to the page and section they need to read or edit having an index to view a site is one of the payoffs for using smart templates when editing and creating your collaborative site the two way web directory creating a new decentralized collaborative web is useless if users don t have an easy way to find and navigate to content that interests them the challenge however is how to provide a centralized place for users to search and find content without creating a single point of failure or control in the network the two way web directory solves this in several ways the two way web directory is actually a virtual portal built into the browser which pulls its data from the p2p mesh and the tagging metadata entered during site creation in the new site wizard this site looks and feels something like a centralized yahoo but is in fact completely peer to peer the user interface for the two way web directory has two major ways of allowing users to find and navigate to sites the first is through search so that users can enter terms into a google like search box and find sites that match their interests the search engine actually initiates a search into the p2p mesh using the various kinds of metadata and content that were entered into two way web sites as described above such as site tags page tags automatic indexation etc the automatic indexation plays a dual role of making it possible for every site to be quickly searched since they are already all indexed the other major user interface is for an automatic yahoo like directory to be created using site tags a folksonomy these site tags are organized alphabetically and by popularity using a flickr like ui the p2p mesh itself also stores information so that related tags can be gleaned allowing users to jump from one site tag to another to find other sites that match their interests conclusion this paper began with a series of questions what if transparent collaboration were a part of web browsers and the web itself what would an extremely integrated network look like with instant messaging site creation and more all integrated into one whole finally what would this network look like if despite the integration it was extremely decentralized paper airplane and the two way web are one answer to these questions empowering end users with a powerful suite of collaboration technologies instant site creation provides one click production of online sites the editor is a powerful tool to get work done with others and an answer to what an internet centric office suite could look like the p2p mesh makes it possible to transparently provide site creation storage naming and saving with zero end user hassle the instant messaging sidebar allows real time communication with site members while browsing and during co operative editing the smart browser technologies standardize navigation tools necessary to make these collaborative sites accessible and organized in a bottom up organic process and finally the two way web directory provides users with a virtual centralized location to search and find sites that match their interests even better all these components work together to create a system that is more powerful than the sum of its parts once a vision like paper airplane is enunciated however it is important to not try to build it instead bits and pieces of it should be taken and drastically simplified with a strong focus on pragmatism and integration into existing systems ted nelson s xanadu is a cautionary tale of what can happen when someone attempts to build a grand vision grand visions are meant to stimulate thinking in new directions not to be built though this paper is focused on creating a vision that pushes our current technological capabilities it is useful to ask whether the system could be built today as described significant engineering and social challenges exist in creating the full paper airplane and two way web peer to peer technology is certainly not up to the job of building the kind of p2p mesh described and fundamental reliability security and performance issues might prevent it from ever being created the current web is also quite entrenched and current trends are towards smaller and lighter web browsers that integrate less features rather than more monolithic integrated ones some of the metadata features such as site and page tagging and the smart templates might be susceptible to spamming and gaming however a great deal of very pragmatic systems can fall out of paper airplane this vision can be sliced and diced into more realistic forms in many different ways that are all quite interesting some possibilities instead of integrating these technologies into the browser they can be brought into existing server side wiki systems using dhtml ajax technologies with the p2p components dropped in favor of conventional client server systems for example the navigator and instant messenger sidebars can be created with advanced html and served up along side a next generation wiki that has a much more powerful editor similar to the advanced editor described in this paper portions of the smart browser can be broken into seperate small firefox plugins developed by different people with simple server side apis and standards for how these browser side smart browser widget work with the remote site for example if a search smart browser component is integrated into the browser remote web sites could implement a simple restian or xml rpc api to be searched in a consistent way by this particular smart browser component the paper airplane browser component could be maintained but could be modified to work with centralized hosting services run by google or yahoo rather than p2p systems for example in this case users and businesses get a powerful collaboration focused next generation web browser but all the functions that were handled by the p2p system instead happen in the centralized computing cluster maintained by a business new apis to link the browser to the server could be created or could use webdav and dynamic dns for the new site wizard automatic domain naming and editing to maintain portability and fairness when moving between different storage providers paper airplane and the two way web can act as an end user research goal for the pure p2p research that is occuring as part of projects like the iris infrastructure for resilient internet systems nsf program a very strong end user product to ground theoretical p2p ideas and provide an easy to understand visible justification aspects of the p2p network could remain but might simply augment and enhance the end user s experience rather than work to replace the existing web for example if the browser has an instant messenger client it could use a spontaneous p2p network between all paper airplane browsers for presence and routing so that existing client server web sites don t have to be changed to support a new standard a p2p mesh can also be an effective way to do dns like naming for example or act as a kind of secondary cache for automatically bittorrenting files above a certain size on the existing web for example simple prototypes of the two way web peer network and the paper airplane browser have been created an open source implementation of the two way web has been created as a prototype framework named p2p sockets p2p sockets is also an experiment in creating a p2p network that exposes an api that is familiar to existing programmers namely the bsd socket interface it also includes higher level ports of software such as web servers the java servlet and jsp apis xml rpc clients and servers etc to a p2p network as well as a simple distributed implementation of the domain name system a...
