A little of Google's time found me BestCrypt and PPDD. Either of these
work external to the disk and would provide plenty of security. What I
really had in mind was a hand-held installation medium for [say] product
update materials, that could easily be read by a Linux target but would
not be 'casually accessible' if lost or pocketed in the field. Ideal would
be a medium that could also be read and written from M$Win hosts and an
approach that made it easy to change keys.

Going beyond my initial situation (and more in the direction of Mike's ALE
talk), is there an approach that would somewhat obscure the unit's
I'm not thinking of industrial-strength security here -- just to
inconvenience the curious.
