Right, which is what we're talking about.

If all my message traffic is on internal only systems (such as the 
social networking you described) then I don't care what my transport 
mechanism is; mail, XMPP, or RFC 1419. It's not going out of my network, 
so I don't even need to use an Internet standard.

So getting back to solving the actual problem at hand ....
