Re: TrueCrypt?
I wonder what the possibility of a device w/ the pin-pad that holds no data, but rather a USB port, a battery and encryption hardware.
I'm thinking it could act as a flow-trough port, and en/decrypt the data on the fly, using the pin and the device ID as the encryption key, or as the look-up to the key in a locally held table. Whatever size/type of drive you hook up to the thing, that's your storage; OS independent; could have versions with 1, 2, or 10 PIN options (5 users, each w/ 2 [regular and duress] PINs) to segregate the market.
