The first application I had in mind was for a password generator and storage
plugin (I keep my DAP with me almost always, and it would be a great aid in
having many secure passwords without having to remember them all). Another
application would be for an encrypting file archiver, although this might be
limited somewhat in speed, depending on the device (it might only work
quickly enough for relatively small files).

DAPs seem to be to be prime candidates for encryption technology, since
their only real downfall as sensitive-information-storage devices is their
tendency to disappear into someone else's hands.
