There is fledgling Multicast UDP support in Twisted, but I don't think
anyone has really tried to use it yet. Are all clients expected to be
on the same subnet? If not, multicast or broadcast is probably not
going to be appropriate.
As far as implementation goes, take a look at the UDP howto, and
echoclient_udp.py and echoserv_udp.py in doc/examples. I haven't used
UDP since the API for using UDP changed, so I can't really help you any
more than that.
