Well, if we pretend that everyone already knows what the "A" stands
for, that's not going to avoid confusion.  Some people still are going
to be wrong.  It would be great if we could settle the matter once and
for all.

I've always thought the A stood for asymmetric, since you're running
multiple cores, but each OS is not aware of the others.  It doesn't
necessarily have to be two copies of Linux.  In fact, it usually
isn't.

As for "MPC8572DS-CAMP", I've always hated that.  A specific property
that defines an AMP environment is a much better idea.
