Fellow wavers, rather than making waves accessible in Google Docs, which takes too long, we are releasing our code in a form that will hopefully be useful in the short term. You can find it at https://code.google.com/p/walkaround/ .
>From the project description: Walkaround is a variant of Wave, based on the Apache Wave code base, that runs on App Engine. Walkaround can import waves from wave.google.com to allow users to keep working with their data regardless of the future of wave.google.com. (The import feature is still experimental.) Much of the walkaround code is not specific to Wave, but factored out as a separate, more general collaboration layer that manages shared live objects. These objects can be modified by multiple clients at the same time, with changes made by any client immediately broadcast to all others. The Wave application is built on top of this, but the live collaboration layer is flexible enough to support other applications. Walkaround supports live concurrent rich-text editing, in-line replies, user avatars, wave gadgets, attachments, and we are working on integrating App Engine's full text search service. For now, it does not support Wave robots, federation, or private replies, but these features could be added. --- Some of you have been asking about Wave on App Engine; perhaps this is what you are looking for. The Wave application in walkaround depends very heavily on the Apache Wave code base, but the general collaboration layer is useful independently, so we put it into a separate repository for now. Happy hacking, Christian.
