Somewhat randomly selecting one to respond to - you guys generated a
lot of chatter.

My view as both a software and hardware engineer on this is simple:
never try to solve a hardware problem with a software solution.  You
will never win.  It is possible to account for many edge cases, but no
matter how paranoid you may be, hardware always trumps software - it
has the last word, regardless of what you may try to do.
