We run our rather large ethernet between several buildings  here at
the University of Texas without a major problem.   Currently we have
a backbone cable running between the CS department and the Computation
Center.  This cable spans three buildings.  Off of this cable we run
several other ethernet cables connected by repeaters and remote
repeaters to several other buildings on campus.  This configuration
kind of stretches the original intent of an ethernet, but seems to 
work fairly well.  Eventually we plan to install a broadband backbone
cable between the buildings and use ethernets within single buildings
only.

I have heard of ground potential problems with running the cable between 
buildings.  So far we have experienced no problems with ground loops
or other such nasty phenomena.
