Hi Mike,

This seems like good news! That made me realize something: as a new usage context for PGP, we CAN require the most stringent level of security and not be worried about backward compatibility. In other words, we don't have to be grandfathering in all the old stuff in PGP - we can require the best set of encryption primitives currently available and baseline on that, and abandon all the older and weaker tech.
