WebRTC Browser to Browser Use cases

Hi Janina,

I thought this could start a useful discussion around WebRTC use cases 
for a11y.. Regarding WebRTC and a11y use cases - you mentioned on a 
recent call that there is no no browser mechanism for a user to control 
media and content. While I've been reviewing the WebRTC Next Version use 
cases, I've also looked at the original 'Web Real-Time Communication Use 
Cases and Requirements' doc, and notice that in 2.3.  Browser-to-Browser 
Use Cases > 2.3.1.  Simple Video Communication Service > 2.3.1.1.  
Description., it mentions clearly that the user needs to be able to:


<quote>

Select to remove and reinsert the self-view as often as desired,

    o  change the sizes of his/her two video displays during the session,
       and

    o  pause the sending of media (audio, video, or both) and mute
       incoming media.

Does that mean that these WebRTC use cases are just not yet implemented 
in browsers?

Please advise if I am missing something.


Thanks


Josh
