The Passive Privacy System proposal only considers the key exchange process. It is hard to see how the key exchange protocol could make an initial offer, having no shared knowledge, while also being undetectable. So the key exchange has to be open. What you do with the keys then is up to you and correctly not specified by PPS.

This seems a strange stance given that another part of RIP says that all your email can be tapped at any ISP and they must not tell you. If you use encryption, this silent tapping is prevented since they have to ask you for the key. And when they do, GnuPG has a mechanism to show only the session key for a specific message, rather than reveal your secret key.
