Tinc already does UDP hole punching, but it requires you to set up at least one
node which is not behind a NAT, or for which you can set up port forwarding.

When you want to invite some one, the invitation must be created on a node that
is not behind NAT or which has port forwarding set up. The invitation protocol
itself runs over TCP.
