fake password technology

All you need is to plug something hot-swappable in, let it get read into memory, and have it add a "salt" to make the hashes of the passwords virtually unbreakable.  Unfortunately, when the system is rebooted, the device will need to be inserted once, which is a small pain.  I guess that's why they sell the hardware fob.  And this won't protect against more sophisticated virus-style attacks and physical theft where a laptop of stored passwords along with the fob is stolen.
