Hi John,

One very tiny correction to your nice summary of issues:

The Intel hardware RNG didn't disappear because it flopped--people ask
me regularly where it went! Rather, its design depended on a particular
manufacturing process, and its delivery vehicle (the chipset hub) became
obsolete at the same time the process technology shifted. This history
underscores the point you were making elsewhere about the implementation
dependent nature of entropy sources.
