How do they have an entire article about a stupid fucking idea like this without mentioning the most obvious point that makes this fantasy unrealistic? Most of us aren't sad hermit people that live by ourselves. For instance, most of the time I buy DVDs, they are kids movies for my 2 year old son to watch. I'm pretty sure he'snot going to be able to work the fingerprint thing himself. And if it uses mine, then how will my wife play these movies when I'm at work? Do we have to buy two copies? What a ridiculous fucking idea.
