Another transport option

This is just a simple TCP transport that will look strikingly similar to
the UNIXSocket transport... Anyway, this allows it to work over the
wire. Keep in mind that I am doing these in the simplest possible way
because I don't expect that the service registration/discovery platform
will see too much in-bound traffic. If that is not the case for you,
make sure to make a Transport that can do some kind of higher-throughput
networking.
