They can DRM it all they want, there will still be people that simply convert it to another format and use it all they want, and there's no way to stop that, really, beyond creating some kind of internet totalitarian state. Which they keep trying to do and failing at, as you occasionally see the odd internet provider suddenly try to "lock down" on piracy, and then suddenly lose all of their business to another provider that doesn't care about DRM.
Like what's happening with AT&T right now, only even more stupid. They may have just committed suicide, by suddenly rewriting their TOS to ban accounts that access streaming television/movies/music, and even sets the stage for similar action against things like Skype, from what I heard. And I have AT&T, because their dsl is the only broadband internet access I can get in this town.
But I'm hoping that this will go the same way all other similar situations have, and that some other provider will sweep in to catch all of the customers that suddenly drop AT&T. Their service is shit, anyway.
