Actually it would be very unlikely that grabbing the hard disk would
enable to boot on another machine since you are restoring all the
context/modules etc. The grabber would need an identical system, and
even then I doubt it would work (I don't know how flexible linux and
the hardware are in this respect.

Its more a question of grabbing you entire computer and getting access
to you hard disk, including encrypted partitions. In this case you
would want to request a key from the user and not use a hardware
related key.
