Just to clarify: xPL uses UDP, so you can't actually connect to the
listening
port.
The xPL hub will bind to UDP port 3865 and start listening for incoming
messages.
The xpldev framework will bind to any free UDP port (> 50,000 ISTR) and
will
then send out an xPL heartbeat message that the hub will pick up.
This heartbeat message contains the port number that xpldev has bound to.
The hub adds this port to an internal list, and whenever any xPL packets
arrive
on port 3865, the hub forwards them on to any port that is registered in
it's
list.

Sounds interesting.
