I think you *might* have lost me here. Is the behavior you're imagining 
something like:

  * Offerer sends an offer with VP8 and H.264
  * Answerer replies with an answer with VP8 and H.264
  * Offerer sends VP8
  * At some later time, the javascript tweaks a knob on the RtpSender,
    and the offerer switches from VP8 to H.264 without any SDP exchanged


If that's the case you have in mind, do you envision that the offerer, 
if he sent a new offer at this point, would exclude VP8 from the offer?
