Oh I assumed that this API was for the widget case -- in HTML4, you can 
already do static image capture and non-streaming video or audio capture, 
using <image type=file accept=...>. It's not widely supported yet, but 
HTML5 elaborated a little on the idea and from talking with browser 
vendors I wouldn't be surprised to see it implemented in the near future.

This seems redundant with existing features. I'd be very reluctant to 
introduce multiple ways to do things.
