There;s a company, Secura PC, that makes a hardware/software device.  You
have a little chip (That can go on your keyring) and you touch it two
these two contacts on bootup, it has a unique, 256bit, key that's read serially
in 1/20 second, and then, when combined with a password, unlocks your 
computer.  Ah, but youc an boot of a floppy, you say.  Not when the program
encrypts every sector on your harddrive.

However, I've had problems getting it to work, I'm not sure if their
encryption scheme is any good (256 bits, come on!) and there's performance
degradation (10-15%) on all harddrive reads/writes.  I'm going to return
it, but am worried they'll rip me off.  Such is life (they've also got
atrocious support - i've called twice and was given bad advice, and I've
left messages, in the middle of the day, and haven't been called back.)
