This is definitely true, but it is good to keep in mind that in the near
future we will start to see things look a little like multiple "virtual
wires."  This is because of new ethernet standards like per-priority
pause, which makes it possible that one hardware ring on a NIC can
transmit while another ring is paused (possibly because of congestion
far off in the network).
