RFC 5764?

I think that's a discussion we need to have in the IETF RTCWEB 
WG-in-formation, though. Will you be in the BOF on Tuesday?

The biggest counterargument I could see coming is that it's going to be 
signficantly harder to make it interoperate with existing SRTP 
deployments that negotiate keys over the signalling channel.
