Miron: The interests of the copyright holders are what they always have been: to ensure proper use of their copyrighted material for which their business model says they get paid.
Content owners would like to distribute widely to as many devices as they can, provided they have the comfort that the distribution is governed. DRM is part of that process.
Consumers would like to be able to freely move content from one place to the next with the ease of use they're already used to with a CD or DVD.
They don't want it tethered to a single device, format or player.
The technology players in between would love to try to keep people locked in to their formats, their devices or distribution channel. So you have a tension of the ends against the middle.
