The last time we got into this discussion, someone mentioned the number of keys that could be used for Blu-ray was on the order of billions. Billions of keys. That's a shit load of keys. It's enough keys that yes, you could disable one single player (not the whole line of a certain model) and still have plenty of keys left. The current world population is approximately 7 billion people. If they can do double or even triple that number of keys, there will be no forseeable shortage.

I do agree that having any form of DRM is pathetic and laughable. I imagine it'll only take a couple of weeks for someone to hack through BD+ and that'll be the end of it.
