I was not addressing interoperability above.  The question I was addressing
is how the security architecture of RTCWeb might be relevant to the
desirable security properties of the Presentation API.  We could provide
perfect interoperability without securing anything, let's not confuse the

I will file a separate issue to discuss the status of interoperability
among implementers and we can get a better sense of where we are at.  Any
standard(s) that form the basis for interoperability should meet the
desired security requirements.
