[K12OSN] Networking a new school for K12LTSP?

[Rob Owens]

To eliminate the ground plane problem, couldn't you
just run a grounding cable from one building to the
other (in the 
same conduit as your network wire).  This seems to me
like it would solve the problem, but I'm not 100% sure
-- and I 
don't know if it is allowed by the electrical code
(but I don't see why it wouldn't be).
