Per the last conference call, we need to first define what the AM will
produce and the value proposition that the AM offers beyond what the
current spec offers. E.g.  how and for what purpose will the AM be used?
We need to have the goals and deliverable for this effort identified and
agreed upon (I guess approved at the F2F), prior to embarking on going
ahead with concrete proposals, IMO.

Regards, Prasad
