    Anyway, there's only one true way to preserve secrecy : close the curtains, close the lights, pop up the volume (hard-rock is best), then whisper in your corespondent's ear "the" information...

    The big problem is that this is using preshared key technology. Very combersome and not ad hoc like email is meant to be. What I have found is Voltage Security has a cool offering that provided true ad hoc email.
