You'd be better off just putting an I-Button connector on
the Pilot (or hanging one off of its serial cable) -- you
want to be able to physically attach and detach the button
at your convenience. (That way, you could drive a nail
through the iButton when you wish to "revoke" your key.)
At last year's JavaOne conference, one of the Dallas
Semiconductor folk showed me a prototype cell phone that
had an iButton connector on the back: all of your personal
phone numbers would be stored on the iButton, and the
phone would only work when held in the hand with the
iButton.
