By way of introduction, I've been working with Greg Clark of DASCOM, Inc., who
spoke with the CAT-WG last Monday on the use of CMS (Cryptographic Message
Syntax) with Kerberos PK-INIT.
I couldn't help but notice, when looking at the upcoming S/MIME Freeware
Library, that its CMS APIs bear a striking resemblence to IDUP-GSS-API. Is
there any joint work planned between the CAT and S/MIME WGs to make
IDUP-GSS-API the standard APIs for generating and consuming CMS messages?
