[Twisted-Python] How to achieve a reliable "connection" over UDP?

[Jim McCoy]

This has already been written, just not in Python.  Take a look at
enet, RakNet, or UDT.  The various variables that will be in play here
are your need for congestion control, whether or not you can live with
out-of-order message delivery, and if you have any need for security
on the channel.
