So, does it find the best route between 2 computers, or just a route? For instance, if half the computers are on a local network together, does it find them via that network, or does it go to the internet and then back to connect them to each other?

The initial configuration requires talking to a node on the internet. But I have two nodes behind the same NAT and they're happy to talk directly using UDP (verified with wireshark), without routing over internet. The standard encryption is still used.

I'd be interested to know if it uses something like STUN/ICE to punch through two different NATs... don't have two NATs to try at the moment.

Thanks! I'm fine with a constant connection to the net, and even locating each computer that way, but I want the computers to then talk directly to each other. (At least until the IPs change, etc.) It sounds like it'll do it. Thanks for the info!
