Course the thing I wonder about that is then would seem to loose some
redundancy,  unless you have a separate network setup to run the serial
over LAN.  Basically stuff like Cyclades is out of band from your
administrative network.  Course I guess if a switch blows up, there may
not be any particular need to access a node.
