Re: [webrtc-extensions] RTP Header Extension Encryption (#47)

I am not sure I understand why "a=cryptex" isn't session-level rather than media level. If an endpoint supports receiving and decrypting cryptex, then it should be able to handle receiving it on any m-line. The above example would most likely be a gateway that fronts a legacy video system that doesn't support cryptex. But in that scenario, why can't the gateway decrypt cryptex and pass it along to the legacy video system in cleartext?
