Hi Pierre

PSD   = proprietary software/data
PSDV  = PSD vendor
Chip  = TPM chip
Owner = PC owner
Key   = a cryptographic key

Chip + "non-free" OS do undermine Owner's control:

PSDV encrypts PSD with Key
PSDV communicates Key to Chip
Chip allows Key to be used by "proper"
unmodified .exe on "proper" OS only

The solution is to build a Free OS so popular
that PSDV shall be forced to support it


Pierre> blackbox algorithms don't require opaque memory

Pierre, I'm extremely interested. Could you tell more? I've assumed
RIAA needs both "non-free" OS + Chip to enforce real DRM
