     As an end-user, using DOM Futures was as simple as including the 
Polyfill JS. Thing is, if WebRTC is built into the browser, I'm guessing 
users would expect all dependencies (i.e. DOM Futures) to be built-in too.

     Seeing as the polyfill JS is rather small. What prevents you 
vendors from folding this into the browser at the same time as WebRTC?
