I'm confused. This makes your servers sound almost entirely useless most of the time. What role do they normally play?

[mbreese]

It sounds like they are using their servers as a relay to get around two clients that are behinds NATs.

[andrewflnr]

Yes, I got that, but what else do they do?

[huhtenberg]

It's a rendezvous service. They help clients locate each other.
