Are we going to start having to carry receipts for everything on our PCs when we do border crossings? How do they even know if you have stuff that violates a copyright? You could have ripped stuff from CD's, or even OCRed a book that you own, or heck, typed it in by hand.
Perhaps
TrueCrypt is the way to go. I think a recent ruling said they couldn't compel the guy to give away his password.
