You're welcome. Added to sourceforge. FYI, MH-E of the Emacs CVS head
already supports S/MIME through the `smime.el' library that uses
openssl. Remember that MH-E uses Gnus MML to provide the security. You
just change the default MML method to "smime" instead of
"pgpmime". However, multiple identity support is lacking, and `smime.el'
has some security, feature, and ease-of-use concerns too.

This is not the only feature I've added to MH-E / MM locally for my own
personal use. Some of these include:
   - proper LDAP email lookup and expansion via EUDC
   - scale-down of large inline images to fit current buffer window
     size; works with Unicode and HTML buffers too!
   - key strokes to switch between smime/pgpmime
   - identity handler for auto signing, different method for each
   - inherit lpr command from `lpr.el'
   - auto-view of PDF, DOC, etc. inline

I concur with Stallman's concern. The Gnus I referred to is Gnus 5.11
(cvs), which now appears to be named No Gnus, current snapshot is
version 0.6. (My code requires the head CVS - 0.7.) Perhaps you can call
this alpha software. You'll note the comments in my example work around
a No Gnus "bug" present in this functionality.

Earlier I read a thread between some combination of EasyPG, Gnus devs,
and/or Stallman -- I don't recall. The general impression was that `epg'
just might replace `pgg' altogether in the future;
code/decisions/interfaces are in flux... etc.

Mostly I hope that MH-E will add this feature soon after No Gnus
reaches a beta/merge/release state :-). Before-hand could be premature,
IMHO.
