My final degree project in Computer Science was an attempt to build a P2P twitter http://code.google.com/p/qantiqa/

Due to personal issues and a tight deadline it was not featureful as I wished but it worked, although there is a central point that works as gateway to the overlay.

Anyway, after this point, it works fully decentralized.

Looks interesting. Is there a human-readable description of the protocol somewhere?
