For XMPP that would include protocol extensions such as <a href='http://www.xmpp.org/extensions/xep-0033.html' rel="nofollow">Extended Stanza Addressing</a> and <a href='http://www.xmpp.org/extensions/xep-0138.html' rel="nofollow">Stream Compression</a>. A future version of the XMPP presence scaling analysis document may discuss such optimizations. Yes, various optimizations would reduce the bandwidth usage.

So if me and another user on my domain are both subscribed Bob's presence, Bob's server only sends out a single stanza to my server when Bob comes and goes. Simply tacking on our extended server addressing element would do the trick and would be transparent to all but the servers.
