Correct you are! Having spent 7 years of my career doing large OSP (OSP in 
this case is Outside Plant) installations around the country including 
direct buried, ducted and aerial I can confirm that these techniques are 
routinely employed. That makes 2 cable weenies!

Gee, makes a good case for putting innerduct inside conduit and putting
gas through it just to discourage BIFF. :-)

Am I the only one who's a cables and switches weenie enough to know
that the telco's _already do this_?  Large numbers of local multi-pair
trunking cables are pressurized with nitrogen, and they put pressure
drop alarms on them, so they know if one takes a hit.
