I must admit that I am troubled by making RSA/IDEA/MD5 a MUST when 2/3s
of those algorithms present patent and license issues.

In fact, it occurs to me that we have the issues back to front.  Perhaps
we should decide what the MUST/SHOULD/MAYs are for the public key
algorithms first.  If we decide something about RSA, be it one or other
of the choices, then as a tougher nut to crack, wouldn't it then have a
fairly serious bearing on IDEA?

For example, there is no point in IDEA being a MUST if RSA is a SHOULD. 
And if RSA is a MUST, I would have thought that whatever the state of
IDEA, it would not indeed be the biggest of issues facing us.

If compatibility with pgp2.6, etc, is a MUST, then RSA is a MUST.  Is
this acceptable?  Have we already made a decision on RSA, or has the
IETF already pronounced (via the S/MIME group) a leaning on this?
