  The old arc-net cards (about 1meg speed wise I
think) used to run on phone wire (even used the RJ11
jacks).  Each card had to either be terminated or
chained to another card.  You couldn't run a phone and
the network on the same cable though.  I can't count
the times the lan admin. used to come into my office
and ask if I'd been playing with the terminator again
:)  If you can find any of these cards they would
probably be less than dirt cheap... but I'm not sure
about the length restrictions.  I've run ethernet over
phone wire too..  stay at 10 meg and you might be able
to use existing phone lines (which are usually cat-3)
but once again you can't run the phone line on it at
the same time.

Kyle.
