Really interesting article over on Slashdot on SEncryption? What Encryption? and discussing how having an encryption program that you can be forced to give up the keys to (or arrested for refusing to) automatically puts you under suspicion, because if you do have some sort of program like TrueCrypt then you must have something to hide. The author goes through the pros and cons of a few different ways, and proposes some interesting ideas of ways for plausibly deniable encryption to become a little bit more mainstream and "normal", and therefor not as much of a red flag that you have evil anti-government subversive videos hidden on your hard drive.
