My understanding was that the stated aim of the exercise is to stop
someone writing software that poses as video hardware to an existing
driver because the hardware & driver do a DH key exchange and the driver
encrypts the "premium" content with the exchanged keys.
Thus if your software was able to masquerade as a plug in video card and
did the DH exchange with the driver you would then be able to decrypt
the "premium" content yourself.
