We agree that playback of premium content is an important use case for the web.  Content creators want to build new, innovative ways for people to enjoy their content within the browser, and we support this initiative as a way to get more content online.

This proposal is a good way to start the conversation, and hopefully we can craft a standards-based system that allows for a diverse set of media use cases to be implemented.  Some people will choose to create applications that utilize content protection, and some people will choose not to.  The web should allow for both.
