This is why you use full disk encryption with a hidden volume, and follow proper practices for keeping both maintained. The computer will be obviously encrypted - but, if done correctly, there will be no way to know there is more than one system in there. (there are plenty of side-channel give-aways though that a thorough investigation might turn up - truecrypt's docs and site explain this better than I ever could) That was off topic - your idea, it is interesting. I wish I had the background to comment on it.
