I don't think that is a good idea, since Blobs are static objects (an immutable array of bytes), and MediaStreams are a constantly-changing stream of media data. So a URL constructed for a MediaStream cannot be used everywhere a Blob could be used, for example it can't be loaded via XmlHttpRequest.

I agree that Blob makes no sense here. But it seems like a better thing might not be a URL scheme but instead just define the object that gets returned and out to get the data out of it.
