Out of curiosity, has anyone *ever* seen one (a dead man switch) in the
field?  I know its something that can be done, and a risk, but I can't
say I've ever heard a report of finding one.  Just curious.  Seems like
every time your DSL or cable modem flaked out, your hard drive would get
formatted :)  Considering my local service, that would mean a lot of OS
re-installs.

Yes, I encountered one on a compromised unix server that I was asked to
investigate.  A normal shutdown would have wiped the system (the real
shutdown program was trojaned so that it would run an external program
that did the work).
