If you do have FDDI, that isn't Fibrechannel.  I used it in 1997 between 
2 Alphas a mile apart.  The main problem was that you didn't see remote 
disks until both systems were up, so a reboot would trigger a full shadow 
copy for the disks shadowed across the 2 sites (this was of course before 
mini-merge came along).

FDDI is only 100 Mbit/s which in the light of your recent enquiries
about Gigabit ethernet might not offer the advantage you require.
