I think that you can stop worrying about lightning strikes.  Usually this
occurs when the cables are EXPOSED, as in "hung up on a tree".  I would suggest
trenching and burying your cables.

If you are concerned about ground potentials, why not simply run coax,
and put a couple of isolators at critical points, such as the nearest
building entrance?  I would strongly suggest tying the ground (shield) of
the cable at that point to a REAL EARTH (read- a big metal pole in the ground).

By the way, somebody made an "isolating repeater" at a very resonable price,
but I cannot find it in my files.

I was really concerned about this problem in the past, but other ones seem to
be much more critical, such as "tromping on the cable", installers who
tie kinks in it, etc.
