An order of magnitude improvement in security?  Hmm.
May I ask, against what kinds of threats?

This is a very interesting claim.  However, after that
teaser, I hope you'll elaborate.  I must admit I'm having
trouble seeing how TCPA would make any difference in
the way I use computers every day.  Boot sector viruses?
I've never gotten one.  Remote verification of trustworthy
boot?  Solves a non-problem (for me); I've never seen
an untrustworthy boot.  Trojen horses in the operating
system?  I've never seen one.  Just about all of my
security problems have been network security problems:
e.g., remote penetrations (say, by buffer overflow) of
privileged applications.  I can't see how TCPA would help
with this problem.

What am I missing?
