It is well past the "live" date, but through the magic of electronic media and the Internet, you can catch Jon Callas' webcast on "The Dawn of Pervasive Encryption" at PGP. You will have to register and I suspect a sales person will e-mail you. I think it would be worth it. Jon talks about solutions that he has proposed for making encryption more widely used. It is a PGP Corporation commercial, but it is rich with techical content.

I've written on this subject before. (See my "Secure E-mail collection" at here.) The technology and related software to easily use encryption has been around for 15 years. Aside from our apparent lack of belief in the need for it, the use of cryptography and the need for some level of ubiquity have been speedbumps for its use. Rather than go through the details, I suggest you listen to the webcast. Also, you can see my review of PGP Universal by going to my "Writings and Musings" page and clicking on Painless PGP.
