Zeromq plus msgpack or the like (maybe cerealed!) gives you quite 
a lot.  I use nanomsg, which is still beta but nicer in some 
ways.  In any case it gives you survey, request/reply, bus, 
publish / subscribe patterns.  And it's very light and has decent 
throughput.  What kind of framework were you thinking of ?  
(nanomsg doesn't do UDP, but I think zeromq does.  You can write 
your own protocol or pattern if the existing ones don't work for 
you, and sounds like that's work, but not much more than it needs 
to be).
