Comment 6 for bug 586663

In this case XMPP(Jabber) may be better.
Because:
* Transports
    * every protocol mentioned above can be _integrated_ into XMPP
* Decentralized by design like email
     * No "borders" like between quakenet/freenode
* Profile has a Jabberfield
     * JabberID is a unique identifier
* Multiple connections allowed
     * API can be distributed over multiple servers / launchpadmodules

A good library exists: xmpppy
http://xmpppy.sourceforge.net/
(git://xmpppy.git.sourceforge.net/gitroot/xmpppy/xmpppy)
