It should be noted that one of the prime purposes of the Trusted
Execution Technology (TXT), aka LaGrande Technology is for DRM
enforcement systems that can be nearly uncrackable.

It can be used for other things, such as restricting who can look at
your medical records (basically, the same technology that prevents you
from breaking the DRM on say, a high-definition movie from Hollywood)
can also be used to enforced who can look at your certain records,
such as medical records in a highly secure and non-circumvental
fashion.

Ross Anderson was one of the first to write about these concerns, over
five years ago:

http://www.cl.cam.ac.uk/~rja14/tcpa-faq.html

It's interesting that his 2003 document was able to predict the
emergence of the LaGrande Technology (see question 15 in the above
FAQ).

So we should expect a certain amount of controversy and people
lobbying to resist the acceptance of this patch.

Regards,

- Ted
