To add to mwcampbell's response, my cofounder Amby proposed a possible solution:

What are your thoughts on this approach?

You probably want to send the accessibility tree in addition to the video stream, not instead of it. Luckily the Chromium accessibility tree can already be serialized and pushed, because Chromium does that between the renderer and browser processes.
