This technique has been around for some time already. Although it works
in many cases, it is quite an hack and an abuse of the UDP protocol. I
don't see any use for it in the context of XMPP.

And if I was a network administrator I would certainly try to block it
in my firewall or make it trigger my IDS.

best wishes,

Winfried
