Technical Summary

   This specification defines an ORIGIN attribute for STUN that can be used
   in similar ways to the HTTP header field of the same name.  WebRTC
   browsers utilizing STUN and TURN would include this attribute which
   would provide servers with additional information about the STUN and
   TURN requests they receive.

   In particular, this draft solves the common problem of running
   "multi-tenant" STUN/TURN servers. For example, WebRTC applications
   running on different domains with different user databases can use the
   same STUN/TURN server when the ORIGIN attribute is supplied by clients.

Working Group Summary

   The draft has been reviewed and discussed by the whole working group.
   The WebRTC community demonstrated interest too. This is a pretty
   consensual document.

   The harder technical issue had to do with the fact that the attribute's
   value can grow quite large and could make STUN packets exceed MTU.

   An IPR declaration regarding the individual draft adopted as this draft 
   was made in 2014, but a second IPR declaration regarding the working 
   group draft listed the draft name in the wrong field of the disclosure form, 
   preventing the second IPR disclosure from being linked to the working 
   group draft in the datatracker. This wasn't discovered until after the first 
   Last Call ended.

   After consultation with the working group chairs, we issued 
   a second Last Call to ensure that if the IPR disclosure changed anyone's
   evaluation of the request for publication as a Proposed Standard. We 
   didn't heard any comments during the second Last Call.

Document Quality

   Client and server open-source implementations have been made available
   ("Chromeo" and "Coturn"). This shepherd expects to see more
   implementations by the WebRTC community shortly.
