Sure, but in order for that approach to work, your XMPP server (or some 
XMPP server) needs to know about and communicate with the STUN servers 
and media relays on the network.

Yes, I can do that by pulling the discovery stuff out of XEP-0176 as 
we've discussed in this thread.

So you communicate with the relay server via XMPP, or you communicate 
with your XMPP server and it communicates with the relay server?

Again, does the XMPP server itself provide the media transport, or just 
show you how to find the STUN servers and media relays?
