Authentication servers, for one. RADIUS uses UDP because it can bang on the 
server knowing that the odd dropped packet won't get in the way of other 
requests, eve if it is requesting them at hundreds or thousands per second. 
But that has congestion issues. The idea here is to be able to side-step a 
few lost requests and retransmit them, *and* have congestion avoidance.
