Objects sent that way are cloned, not transferred, and are still usable on the sending side after being sent. This way, we don't have to define what a neutered MediaStream is and "ownership" will always be kept by the page that has done getUserMedia() or contains the PeerConnection instance that feeds a remote stream. /Adam [1] http://dev.w3.org/html5/postmsg/#posting-messages
