Hmmm... That's an interesting idea! The only problem; your data isn't secure to anybody with a MacOS X install disk who knows how to use the Reset Admin Password thing, is it? They could reset your password, and the encrypted volume would still open with the newly reset password when the same user logs in. But a great idea for cases where physical access to the machine is restricted and you want to get a little extra security... Personally, I think it's a GOOD thing that it's not totally secure; I work in computer repair and we'd probably end up seeing a few people with forgotten passwords wanting us to attempt data recovery.
