How about including a S/MIME gateway
The OpenGroup and Blake B are reportedly
working on such a thing.
What happened with the gateway BOF that Phill H-B
wrote about sometime ago?
An S/MIME gateway standard is really needed as
S/MIME end-to-end encryption is not going anywhere.

Subject: Charter Modification
To include Stefan's work in the working group we
need to modify the working group's charter (we also needed to update the dates
anyway because some are way off). Attached is the proposed
modification. Please respond with any comments by
S/MIME Mail Security
General Discussion: ietf-smime@xxxxxxx
Description of Working Group:
S/MIME Working Group has completed a series of Proposed Standards that
comprise the S/MIME version 3.1 specification. As part of the specification
update, a new suite of "mandatory to implement" algorithms was be selected.
Current efforts update and build upon these base specifications.
Cryptographic Message Syntax (CMS) (RFC 3852) is cryptographic algorithm
independent, yet there is always more than one way to use any algorithm. To
ensure interoperability, each algorithm should have a specification that
describes its use with CMS. Specifications for the use of additional
cryptographic algorithms will be developed.
To aid implementers,
documents containing example output for CMS will be collected and published.
Some of the examples will include structures and signed attributes defined in
the Enhanced SecurityServices (ESS) (RFC 2634) document.
CMS, as well
as S/MIME version 3 and later, permit the use of previously distributed
symmetric key-encryption keys. Specifications for the distribution of
symmetric key-encryption keys to multiple message recipients will be
developed. Mail List Agents (MLAs) areone user of symmetric key-encryption
keys. The specification will be algorithm independent.
To aid initial
determination of recipient's cryptographic capabilities a specification will
be developed allowing S/MIME capabilities to be stored and asserted in X.509
certificates based on the X.509 certificate and CRL profile developed by the
PKIX Working Group.
The working group will perform necessary
interoperability testing to rogress the CMS and S/MIME specifications to Draft
Standard. The CMS specification depends on the RFC 3280. This profile must
progress to Draft Standard before CMS and the other S/MIME specifications can
progress to Draft Standard. Assuming timely progress by the PKIX Working
Group, the S/MIME specification can start progressing to Draft Standard in
compressed data content type a Proposed Standard.
