Haha, love that. Although you might as well read HTTP headers to each other on the phone

Does this still work? Haven't they added a timeout to close open ports for security reasons after some time that is too short for human interaction?

This approach has been really helpful to me, as I often work on networks without Internet access (also for a long time setting up your own local signaling server was somewhat of a pain).

Hehe, I did this in my first implementation.

But I guess you'd still need a STUN server?

That's amazing.
