Might be interesting to do some traffic analysis and find out what it
actually does.

Most folk are behind a NAT device of some description or other,
purporting to only allow outbound connections.  But it turns out that if
at least one end is behind a really cheap NAT device, it's possible to
trick it into thinking an inbound connection is outbound and get a
session going.  See Wikipedia on NAT Traversal and Hole Punching.  Linux
and BSD NAT implementations are too smart to fall for this, though, and
denizens of this list might just have a leaning toward Linux devices.

There's a chance it would fall back to going via a public server if it
can't open traversal between a pair of endpoints.
