I mean using PGP/MIME the same way RFC 3923 uses S/MIME.

Yes, I put the * symbol because there were several draft versions of
that spec :-)

You mean in the meantime that a more safe spec is drafted?

Sure! Because my needs are "mobile-oriented", I have to implement some
e2e solution that works when both users are online or not (something
like offline-storage OTR?). Of course an "offline" solution is less
safe than an online one, but of course there might be a compromise
(warning the user that e.g. forward secrecy might be compromised
because recipient is offline might be an option). Anyway, please keep
this in mind when you will discuss your new Internet-Draft.
