I was wondering if there was an P2P Email technology? If so, could you suggest it (or one of them) to me for investigation. If not, is there a reason why this can't work? Or, is there a reason that one would not want to use such a technology?
FreeMail is an in-freenet mail. Also i2p provides something.
Also there is mixmaster network:
