May you post a link to it?

Subjected to a warning, I think this feature would be useful for
trusted peers by sharing each one's current IP address with an other
peer for the purpose of having a backup mean of communication, in case
an XMPP server is not functioning properly, though DHT is much
preferable for the reason I wrote above. See http://telehash.org/

There is a Qt3 VoIP project called I Hear U which is a server-less
IP-to-IP telephone http://ihu.sourceforge.net/
