No. I already skip the ads in the beginning of DVDs, because my free
software DVD player doesn't obey the rule that it should not permit me
to skip the ads.

I'm not sure. It needs serveral layers on top of TPM to be implemented:
it needs tivoized hardware and a tivoized OS on it that runs only
software that implements DRM (Digital Reeducation of Mobility in the
case you describe...).
This is much more than providing attestation of running software, secure
channels and protected storage. Maybe this is the very goal of TPM, but
it's not that obvious that it's its natural use. Let's not throw the
baby with the water. Even if the water stinks and the parents are very

Though variations could. In a novel she's writing, a friend of mine
describe a world where many people own some sort of PDA, which on
selected times shows mandatory news. Of course, you see mostly the bad
terrorists killing the good people like you, and this keeps people in
hatred and fear...

Sure. But I'm sure the battlefield is the law, not the computer.

BTW, I'm curious how fast we'll see automatized software running on
stock hardware (or relatively cheap one) that does this.

I tend to believe that we could press everyone to share by example.
Furthermore, some people won't be able to pay to access the protected
content, like emergent countries in their whole and many poor people in
richer countries. They will probably like very much the open content,
and this can just contaminate everyone.
Generosity, beauty and openness, when a critical mass is reached, can
spread in a stronger way than desire for protection, jealousy and the
like, I think.
