Kevdog, you're awesome.

On that note, could you perchance explain, step-by-step, how to go about each of the layers of this privacy onion? Or, barring that, point me to a tutorial on each of the necessary set-up processes?

Also, will your proposed setup function well with a mail server running alongside? And, if so, how should I modify the component programs of the mail server in order to integrate with the privacy system?
