PGP Universal - Usable Email Security?

An anonymous reader writes "For years, noted cypherpunks such as Brad Templeton, Ian Goldberg (PDF link), Bram Cohen, and Len Sassaman (PDF link) have been calling for easy to use email encryption solutions which involve little crypto comprehension on the part of the user. Now, it seems like someone has listened: PGP Corporation has announced its PGP Universal, which says it 'shifts the burden of securing email messages and attachments from the desktop to the network in a way that is automatic and entirely transparent to users'." The Register has more information on these newly announced proxy servers.
