AFAIK, there's no way for a plugin to interact with a <video> tag in this way. If browsers were to provide one it would be browser-specific. If we were going the browser-specific route we might as well have browser-specific methods on the <video> element - this would be cleaner. If we standardized such an interaction we might as well standardize it on <video> for the same reason.

I'm not sure what you mean. AFAIK you can't modify browser <video> capabilities using existing plugin APIs.

HTML display has worked for audio. I'm assuming that Pandora dropped support of the <audio> tag because it was poorly implemented by many vendors; bugs are still very-much around.
