Have you had a chance to look at the SLOB layer in google walkaround [1]?

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.

It's apache licensed, and took at least some insperation from ShareJS.
