The current real Mac Pro actually has two ethernet ports too. There are a number of ways this could be useful.
Number one would obviously be to connect to two different networks. It could also be useful in a scenario where the machine is used as a server and you want a semi-redundant backup network line. It could also be used to directly connect to a NAS box via Ethernet.
