For the HF buoy I daydream about from time to time I was planning to use
a hall sensor so that a properly placed external magnet would turn off
the buoy.  I figured a metal plate on the inside would give it something
to stick to, and the sensor would be weak enough to require some super-
strong magnet (like one out of an old harddrive).  Then the magnet would
have a float that would remove it in case of accidental deployment w/
magnet.
