I am yet to test this. But, shouldn't you start up a their_endpoint instance with a running udp_listen() thread - ideally on a different machine?
I could do that, it was just easier with this set up to have their_endpoint be the same machine . In later parts I communicate with different machines using this protocol - in part 2 actually!
