I don't think that's true. In fact, the draft <device> element is
providing a solution to both points Harald made:
* control over mircophone
* input of stream of data rather than a file

See http://www.whatwg.org/specs/web-apps/current-work/complete/commands.html#devices

Also see Ericsson's trial implementations for RTC in a series of
