[jdev] Question about XMPP authentication

Why not just run an XMPP federated server and have it configured to  
connect and use Server-to-server communication?

You can then have your web conference software create accounts and  
login to your own server.  Then have you server become part of a  
federation with other servers.

Thanks,
Chris
