More linky's on cool stuff! Reminded me about Distributed Systems lectures in security :)

Safe E-mailing for Dummies
This reminded me about Hushmail, which I used long ago. However, this one seems more secure and versatile since Hushmail was really only secure amongst Hushmail users. Ciphire Mail is more versatile not because it doesn't mean the person on the receiving end doesn't have to be a Ciphire Mail user, but more because it works with your mail client...almost any mail client from the sounds of it. That said, it's in a very very beta mode but nevertheless, sounds like something neat :)

By extension, here are some of the links they mentioned in the article:
