1.07 RSA support questions (Larry Ellis)

I think perhaps that some of your primary questions have
gone unanswered here.  Surprising, because you've
been responded to by some people very important to
the gpg development effort.  Perhaps my understanding
of your question is wrong.  Was it:

1) How to select IDEA for certain encryption events

or

2) How to automatically use IDEA whenever an RSA
Legacy public key is used to encrypt

or

3) How to always use IDEA
