We're currently talking about the (hypothetical) features of the
hardware in my questionnaire -- i.e. CPUs that support a "web of trust" or
at least require a signature from the computer's owner or a trusted
third party (designated by the owner). I.e. not TCPA, but what TCPA
should be, and could be if someone pushed hard enough in that direction,
since it does what the TCPA is all about -- copy protection and trusted
executables -- however it creates a free market in which customers can
decide what to buy.=20

I'd say protection from binary viruses and stack overflows, plus if
someone breaks into your computer and you have stored your key in a safe
place you can tell what she modified. So this would be a definitve must
if you're builing a server, and I'm asking now whether you would like
those features on your home box as well, even if you had to give up DVD
copying or get special illegal hardware for it.

Basically I'm on your side -- but I fear that if noone speaks up and
points out a better alternative, we will be stuck with TCPA as it
currently is, and lose the options we currently have anyway (since we
cannot decrypt stuff from the Internet or from DVDs on our hardware). So
I'm searching for a better alternative. I'm ignoring all the copy
protection stuff since it will be broken withing a few moths anyway, and
just concentrate on the stuff M$ invented against the OSS people.

Your old computers cannot do evil things -- they cannot access media
created since the TCPA rollout.

Most of them will need to start supporting other OSes first. Also, as a
hardware vendor, you may not support non-TCPA OSes, except if you take
care that no unencrypted data leaves the sandbox (which makes the
hardware pretty unusable).
