UDP might work well. There are potential problems with packets being lost,
or recieved out of sequence, or fragmented.
The more reliability we try to layer on udp, the closer we get to tcp.
UDP would make the most sense for rapid polling and monitoring applications,
where lost packets are not an issue.
