What the hell is wrong with real time capabilities (I won't comment on open source DRM, except to say it would make an okay April first joke)? The web needs them, if it is to become the future we always wanted.
WebRTC is good; the question is whether it should use VP8 or H.264. Apple will argue for H.264 while Mozilla will argue for VP8. Since WebRTC has not been deployed yet there is no status quo to create path dependence.
