I tend to think that in the link-local case the most interesting case is 
the multiple user one (imagine doing that at a conference or in a office).

Maybe it could even be done electing a peer as arbitrator, but if it is 
really distributed it would be a lot better (no election, no arbitrator 
going away).

I know that the Abiword people have something similar in AbiCollab 
running over DBus tunnelled in XMMP, so it may be useful to look at 
their conflict resolution algorithm and their way to send changes.

Complimenti per l'ottima scelta.
