So the only solution is to make the propriety, closed-source CDM blob independent from the browser. Something that can be plugged into any browser. Like Flash or Silverlight. Or maybe something more specialized that just handles the DRM with as little overhead as possible, to make sure it doesn't eat up more CPU than it should.

If it cannot be open, it cannot be part of browsers that are open, which a lot of browsers are.
