Re: Not Going to Work
Ok, so in 'theory' in order to prosecute you under RIPA, they would have to be able to prove you ever had a key for something that may or may not exist.
They can't prove you do have a hidden volume just as you can't prove you don't.
The ridiculous would be a large text document where every 4th word is used to make the real document. They can't demand you produce a decypher key for every single file/document I have (ok they can demand it, but they have to prove that encryption is in place) - not that I'd trust that as my only defence you understand ;)
I personally don't use hidden volumes, but I do use truecrypt on every USB stick and hard drive in my posession to protect my personal data in case of theft.
