I have an application for exactly that behaviour.
It's a secure appliance.  Users don't run
code on it.  It needs to be able
to verify that it's running the authorized OS and software
and that new software is authorized.
(it does it already, but a TCPA chip might do it better).

So a question for the TCPA proponents (or opponents):
how would I do that using TCPA?
