Google Wave and Sugar: what's next?

So, yesterday I posted a entry discussing how Google Wave actually implements the collaborative vision Sugar (and OLPC) were working towards. (It's a shame we didn't have better contacts with Google while I was at OLPC; Google was actually on OLPC's board, and beta-ing Waves would have been a very fruitful partnership.)

If you agree with the premise: what should the next steps in a Waves-ification of Sugar be? Eventually Google promises to release "the lion's share" of its source code, for both server and client, so getting the google server installed on the school server is one task — but not one which can be done immediately. Implementing Network Principles is another necessary precondition, in order to use Wave's DNS-based participant naming system ("" or whatever). That's something which can be done now. What else?

Eventually, when the source code drops, making the waves client work offline would be important, since Waves (and embedded gadgets) basically replace Write and Sugar's bulletin board. Waves edit XML trees, so porting existing activities to use XML-based file formats will go far in integrating them into a new Wave World Order. I haven't seen any demo of a waves-based drawing activity/gadget (tuxpaint is a favorite of most kids), so Waves Paint would be a fun project if you want to start playing with the Waves extension APIs.

More controversially, work on Waves-enabling a next-gen Journal could be interesting. As predicted by proponents of the Journal for some time, the "wave of the future" (so to speak) is filesystem-independent storage. Waves in Google's demo are titled and searched like email messages, not as "documents" in a filesystem hierarchy. However, we had repeated requests to unify Journal storage and traditional filesystems, for (a) better interoperability with existing systems, and (b) sneakernet collaboration. In my mind, this would mean exporting a waves-like view of an existing filesystem, as I proposed for the Journal, where directories are interpreted as slightly-special tag markers. One could imagine implementing a "Wave Server" based around this idea, in effect using the filesystem as the wave database. With the magic of Wave Federation, these "filesystem" waves can interoperate with other wave clients and servers. This standalone file-based server might also server as the basis for "one child under a tree" wave editing. (For that matter, a robust sneakernet implementation of the Wave Federation Protocol would also be very useful!)

Exciting times! Wave promises to bring OLPC/Sugar's vision of ubiquitous collaboration to life at long last. Google has the funding and development resources to tackle what is in effect a bottom-up reorganization of the software stack. OLPC/SugarLab's role is peripheral but vital: strongly lead the development of offline or "flakey connectivity" aspects of this technology so that it can be used everywhere from the solar-powered jungle to the dense urban cities, and to provide the educational software on top of the platform so that kids can *learn* as they collaborate and create.
