Well that's cool. Except, as others here have noted: what assurances do you have on the other end (destination)? You can have all the encryption you want, but

Well that's cool. Except, as others here have noted: what assurances do you have on the other end (destination)? You can have all the encryption you want, but ultimately "they" (NSA, FBI, CIA, whoever) have a thousand ways to get at the information they want: keyloggers, 0-days to get into your machine, 0-days to get into your email server, etc. Sure it's a fun exercise, but don't kid yourself into thinking that you're bulletproof. Whether you agree with it or not, the NSA can more than likely get around any protection you try to implement, if they have enough reason to put the effort into it.
