these are all high-level requirements you are phrasing. 

It would be very helpful that someone (is there a responsible point-of-contact) puts down some much more concrete requirements.

For example, you talking about timing, and something being "too late". Too late for what?
- What is the time plan? 
- What are expected outcomes and deliverables? 
- What are the requirements for these outcomes?

W3C or W3C Web and TV IG needs to define this and communicate to the other organisations in order for other organisations and member companies to be able to act accordingly.
Organisations and/or member of these organisations can act and may be able to act quickly, but they can not act based on hallway discussions, high-level e-mail discussions and so on.

I may have missed this information as I was only attending the second workshop, but if these concrete project plans are available, it would be great to get pointers to those.
