I think I should by now at least mention that I appreciate the above
reference. I've started to dig into it, but it looks like it will take me
some time (e.g. not before this weekend now), so I thought I should
at least acknowledge the value to me of the reference.
I'm quite interested to see what such a device provides and
whether one might be able to leverage such technology to
effectively protect capabilities as "data" in memory (disk, etc.),
along with the perhaps wider issue of protection of private
keys. That later is where I'm initially focusing my attention.
