Allo,

The best starter point to build this kind of stuff is probably to adapt
an issue of the Mark's mc-based sockets client/server stack to your own
needs. I use, for my own, time to time, this method to build some very
usefull lan mc-based utilities. See below what Mark wrote, a while ago,
to explain us how to do :
