You might try a upd multicast socket.  One process can send to the
multicast socket and other processes can listen to it.  If they get
the packet they can deal with it, and otherwise it just disappears
into the aether.  It worked well for an conferencing internet
telephone I once worked on, and it has the added advantage that the
processes need not be on the same physical machine.
