I'd love to know what's unclear about this statement. Am talking
*anywhere* in here about long-term charge retention being the mechanism
that allows recovery of the key? Of course not
I am afraid the boundary of analyzing the problem looking only at the
possibility of long-term chage retention was imposed by your mind (and
lack of knowledge) alone. Which... brings me back to the remainder of my
original post.
