Hrm.  I think I agree with you there- since the point is to do better
with this problem than software, (a lot better), it could be argued to
be a particularly un-kosher place for blackbox hardware.

;) I can see where that line of reasoning goes.

Yet, I'd say we can *always* use better HW entropy sources,
(particularly ones which are cheap and replacable if they are
compromised- like these USB sticks).

Where can my headless, microphone-less head-less servers get their
entropy?  What if I even disabled entropy seeding/harvesting in the NIC
because it doesn't really do any good with my app/use?

If you know a good way out of these issues without hardware interfaces
to the "real and random" world, I'm all ears!
