Script and instruction at

Combo of
- Perl for Installation,
- ssh-keygen for key exchange.
- udev for actions
- bash for locking/unlocking/key checking.

udev add/remove/change events
- add event does not allow access to drive
- change event was not allowing unlock.

Great technique

This technique seems like a great way to allow my loved ones to have an emergency "skeleton key" for all of my computers... in case that hypothetical "bus" ever shows up.

Thanks so much for the tip!
