        If it's a serial connection, then only one process can have that 
port open at any one point in time.  If it's a TCP connection, then 
depending on how the server is implemented, only one process at a 
time can be talking to the server.

        Since the amount of data is relatively small, it should easily 
fit into a single UDP packet, which makes the service much, much more 

        Think about trying to do DNS (with a forking or select()-based 
server that allows multiple client processes to be talking to the 
same server at the same time) with just TCP and not UDP.  If only 
because of the much heavier connection set-up requirements, you could 
only handle 1/10th the amount of traffic/connections/etc....
