It'd be interesting to see how your (and other's) setup have endured actual attacks. As someone non-versed in security, I think your approach sounds great. But how does it fare when someone comes knocking?

I wonder the same thing about my setups. I have a password manager with random passwords for every site/forum that I encounter. It'd be nice to know of the efficacy of this work - has it helped me in any way? I'll never know.
