i raised the issue here https://github.com/addyosmani/getUserMedia.js/issues/2#issue... (and suggested a possible solution), but for this we would need the help of a flash megamind-ninja.
It would be really nice to have it using the same API, but yeah, it would be really tricky to actually pull it off.
Then again, I heard about gifsockets (http://github.com/videlalvaro/gifsockets) earlier today, so I guess anything is possible!
