The IETF could eliminate SMTP over TLS (RFC 3207), because it's
hop-by-hop security (only works well _within_ an enterprise
network, which is of course one of the best IPP environments).
But both S/MIME v3 and OpenPGP are recent and Proposed Std.
Do you know if OpenPGP is any more common in infrastructure
and clients than S/MIME? Annecdotally, the IETF Registrar
(for conferences), the RFC Editor and others regularly post
their OpenPGP public keys on their Web pages, but I don't
see S/MIME keys usually.

I'd say that that would be the best route, although the IETF might want
us to narrow the focus to one method?
