This is somewhat off topic but have you tried any ethernet surge
protectors? I use them here in the jungle with lots of lightning and it
works good if your overall install is sound. Also you have to have your
electrical ground tied to the conduit so it all stays at the same potential.
But still fiber is the way to go. You could also go wireless with a pair of
Ubiquiti Nanostation M2's

Greg,

Yes, that's the part about "5-port switch after the surge suppressors on the
cable after building entry".

Immediately after building entry I use HyperLink HGLN-CAT6 Lightning
Protectors  (See: http://www.l-com.com/item.aspx?id=22171 )

Then I connect to a "throwaway" 5-port switch (whatever was on sale last
time I ran out).  This switch is connected to it's own throwaway UPS, which
is plugged into a separate power circuit from everything else.

[[[ Note: If I could find cheap enough switches with an optical interface I
would be switching to optical at this point! ]]]

Then I connect from the throwaway switch to the real switch.

But STILL I lose ports on the real switch from time to time.  So converting
the outside plant to fiber is a real goal.

And the fiber prices are darn reasonable nowadays for 6 or 12 strands of
9/125:  (Example http://www.showmecables.com/viewItem.asp?idProduct=10493  )

But outside plant fiber was never my thing, and I have no decent idea about
how to get it spliced and terminated for reasonable costs, or really even
what would be reasonable.
