Biometric devices can be bypassed. They are just program with a database and what can we do with programs and databases? They are as good as a password and have good uses but not foolproof. I own a **** ton of DVDs and I am with this:
DVDs are digital, your TV is an external device. Intercept the stream of audi and video through DVI and burn hollywood to hell.I agree with nihil. Something like this would make me begin to pirate DVDs, something which I do not do at the moment.
//EDIT As HD DVDs are developed I would expect some new antipiracy inovation. Which I don't give a squat about but digital rights or verification measures are not cool.
