What you've described would be excellent.

It just surprises me that tool like Outlook do not already do this.  And the third party tools that try (I've tried using them) are still a bit clunky and not up with the latest versions.

It almost seems like the agenda is 'don't implement PGP in Outlook, we don't want to upset our friends who gather a lot of business intelligence by keeping email unencrypted'
