When I responded, I should have added what Eli later said in the thread, though:

There's no reason why the underlying (C level) implementation of buffers should 
matter here.  I expect that collaborative editing can be successfully 
implemented entirely in Elisp; it would be very, very surprising if you need to 
look at or even understand anything at the C level for this.
