Hi Ben,

Removing the flash dependency would result in native capabilities for
interacting with media built in to the browser.
For example, in Firefox both the audio and video elements default controls
can be operated using the keyboard.
The controls while not represented in the DOM are represented in the
accessibility tree so that assistive technology can provide access to users
This is not the case with Flash on non windows platfroms..

One of the promoted benefits of HTML5 is built in accessibility, this is
the case for <audio> and <video>
users are less reliant on developers doing the right thing.

Note: this is not an argument for or against CDM's, it's an argument for
providing use of native HTML5 video and audio over embedded inaccessible
