  10baseT and 100baseT use differential signalling, not single-ended
with common ground.

  I'd definitely use fiber for the inter-house runs, though.  A friend
and I ran about a 150' span of 10baseT between our houses a few years
ago...we lost about two 10baseT transceivers per year due to EMP from
nearby lightning strikes.  Fiber obviously doesn't have that problem.
