I personally have grave concerns about this technology, independent of
who is advancing it- just reading the links you provide makes it clear
that its primary purpose is to restrict the degree of control a user can
exercise over their own data, programs, and machine. Is it any wonder
that the same people who find DRM abhorrent find the technologies
used to advance it equally distasteful?

Besides sealed storage and memory curtaining- which I admit have
seductive security implications- all of the supposed advantages
of a TPM can be replicated using non-interactive zero knowledge
proofs. I'd rather we put that capability into the standard library-
but I strongly doubt that's going to happen any time soon.

I also suspect that if this were a simple undertaking, there wouldn't
be a 'we' in this sentence.

If you were suggesting adding a crypto API to python, I'd be all
for it- but you're suggesting adding the ability to have Python
software vendors remotely cripple the code on your machine.
I just can't get behind that, and while you're sure to hear wildly
divergent opinions on this board, I suspect that mine will not
be an uncommon sentiment.
