Silvia,

How nice to see you on this list. For those who don't know, Silvia and I
both participate in W3C's HTML 5 Media accessibility work where we are
surfacing some candidate requirements on accessibility APIs.

This conversation thread looks like a good start to me.

However, we should regard this as early process, e.g. we've not even
identified all the relevant use cases yet in the W3C conversation.
