Looks like it. :)

What you are talking about doesn't need new markup. It is already possible and done many times over with text sitting near the video element that is marked up for navigation. TED talks expose this feature and YouTube videos have it, too - where a transcript is available. It should be the recommended way to provide transcripts on the video page and I have it as part of a set of 'best practices' that I am collecting.

The problem we are dealing with for @transcript is for deaf-blind users and for browsers that cannot render any audio or video. And then more generally everyone who doesn't care to watch the video but quickly wants to scan the transcript.

Hope this helps.
