I've also been looking into UDP. In my scenarios usually low latency is 
more important than reliability. (e.g. OSC controlled instruments, MIDI 
setups, ArtNET controlled lights) UDP is almost always the choice then. 
I've been using 0mq for a while now and I really really like it but I 
foresee I will need to revert to UDP again once TCP gets in the way.
