Hmmm. The WebRTC stack has a pretty explicit form of getting and then maintaining consent; it also rides on top of UDP (SRTP/UDP for media and SCTP/DTLS/UDP for data channels). Because both media and data channels go from peer to peer, it has no preset group of server addresses to white list (the only way I can see to do that would be to force the use of TURN and white list the TURN server, but that would be problematic for performance). How will you support it if the default is to throttle UDP? Clue welcome, Ted
