Clever. :) The core mechanism should be slightly less effective than normal
STUN. What's novel about it is that it doesn't require an external signaling
channel. It is quite "hacky" though. Particularly the ICMP trick would send
lots of useless packets when you're not using the service. But, if you have
a strong need to set up a proxy server on a network where you have no NAT
control and don't want to have to use or maintain an intermediary service to
act as a signaling channel, then this looks like a neat tool.
It probably has no fit with XMPP though. We have a signaling channel where we
can use STUN correctly. And we can do more than just STUN, too.
