PPS is primarily a protocol for public-key cryptography key-exchange.
It is important to remember that PPS is not, by default, about securely
encrypting your email, it's just a way to get some of the hard work of
cryptography out of the way.
5/9 -- PPS IS NOT DEAD! I just want to let folks know that I've just
started a new job, and PPS will be a bit slow in development for a bit.
As I get settled in, work on PPS will resume.
If you want to get involved drop me some mail, and I will be happy to
parsel out work on the spec, reference library or plug-ins.
3/27 -- The SourceForge site will be going up this week. Also, major
