*
* UDP Client is really a UDP server
2016-01-04 20:22:37 +11:00
*
* Dedicated UDP sockets on the same
* machine can not be bound to in the
* traditional client/server method
2016-01-04 20:22:37 +11:00
*
* Every UDP socket is it's own UDP server
* And so must have a unique port on its
* machine, unlike TCP or Unix Sockts
* which can share on the same machine.
2016-01-04 20:22:37 +11:00
*
* Since there is no open client server
* relationship, you should start world
* first and then hello.
