[Paul Gardner-Stephen]

Hello,

In principle this sounds like it should be possible.

Thinking from a Serval perspective, the p2p discovery could be used to
identify which peer to connect to as you describe.  Rhizome could announce
the head of each peer's data store, which the peers could use to work out
when other peers have new content that they wish to synchronise.

Maybe we should get a student working on trying to implement all of these
novel data paths next semester.

Paul.
