Lexmar has a usb drive called the JumpDrive Secure II which touts:
JumpDrive Secure II comes preloaded with advanced security software that lets you protect your data securely, quickly and easily. Creating a secure area using both password protection and 256-bit AES encryption is a snap. Simply drag files to the secure area and JumpDrive Secure II encrypts your files for you. Drag them out and it will decrypt them for you. Secure II software is cross-platform so you can secure data and access it on PCs and Macs.
I’m telling you, if you can get this Bluetooth or Wifi enabled, and add some sort of syncing mechanism (for backups) in case you lose it or it breaks… I find that all fascinating.
