Hello All,

Here at Jive Software we've implemented an UDP handshake that doesn't use STUN. We are finishing the XEP Draft in the next week.
It can be used with UDP Raw and also with ICE, with excellent reliability.

Best Regards,
Thiago

Right. But that doesn't help us with the raw UDP transport...
