There are some other solutions out there: for example the NSA/DOD approved
Cylink Corporation product that puts a fiberoptic wire across the cable
pipe.  When the pipe is knocked too hard or cut into, the vibration is
detected by the FO wire and an alarm sounds.  Similar to Drew's
pressurization suggestion above.  The alarms can be set to ignore
vibrations up to a certain level so as not to create too many false
alarms.  This is a great solution for situations where you are running wire
under ground between buildings on a business campus.
