To the best of my knowledge, the Server and Clients make _initial_
contact over the "well-known tcp ports" 6000 + n  where n equals
your display number (eg, foo:0.0 uses port 6000, foo:3.4 uses port 6003).
Once the initial connection and verifications are made, a unique
port is agreed upon (how, I'm not sure) for further server/client 
communications on a per client basis.
