alvestrand has just created a new issue for 

== Change SetLocalDescription to require unchanged offer/answer string
As per discussions at IETF RTCWEB meeting in Seoul - it was decided 
some time ago to remove the ability to change the SDP string between 
createOffer / createAnswer and setLocalDescription. In Seoul, the 
decision was that a createOffer / answer invalidates all previous 
descriptions, and increments the version counter - only the last 
version number can be set with setLocalDescription.

This needs to be reflected in the webrtc-pc spec.

A proposal was also made that setLocalDescription's argumet could omit
 the SDP string and that this would cause the last SDP created with 
createOffer/createAnswer to be used - since this is strictly an API 
matter, this ought to be a WEBRTC WG concern.

WG consensus on this needs to be established before doing it.
