Ignoring how iChat may or may not do it, I figure the most straightforward 
answer would be to have the clients perform the xmpp-core s2s protocol with 
each other.  JIDs become user at workstation.

What we just need then is some document explaining the zeroconf process of 
locating local Jabber servers, both for xmpp-client and xmpp-server, and a 
way to query an xmpp-server for its users.

The xmpp-server type could be either a "real" server (in the Jive sense), or 
an ad-hoc rendezvous-style workstation hosting a single user.  To outsiders, 
it really makes no difference.

Finally, although not strictly necessary, a nice iq protocol for "normal" 
Jabber clients to access the above features via an intermediate Jabber server 
would make it easier for existing clients to become ad-hoc aware.
