It sounds like you want to do the same thing: design a protocol
that includes some kind of message that's agreed to mean, "Yo,
make a new connection on this port." Basically, any

Yeah, I was hoping it would be 'redirect to this port instead'
so you wouldn't have to make a new connection. With port
forwarding and other issues involved, I can see a big problem.
Once you are using a port I'm pretty sure it will be locked
(although if multiple can share the same port, I'd be fine with
that too, as long as I know what IP address it came from).
I suppose I can simply write it and try to get it working...
