Is this interoperable with WebRTC nodes, or is it a fork?

  It's my understanding that ORTC was originally proposed by Microsoft as an alternative to WebRTC. I've never been able to track down what MS thinks was actually wrong enough with WebRTC that required an alternate proposal.

      As someone that has spent the last 18months building on WebRTC I can agree with all of Microsofts points - particularly offer/answer state machine which is hugely problematic.

    I don't know about the other stuff, but Microsoft hated having to use the VP8 codec instead of h.264 (even though it adopted it later on in Skype).

If they went through the trouble of overhauling WebRTC, did they at least add better end-to-end security to it?
- sthustfo 12y ago
  It is basically WebRTC, but without SDP and Offer/Answer mechanism.

You can find discussion of various aspects of ORTC's design on the public mailing list archive for the ORTC community group here: http://lists.w3.org/Archives/Public/public-ortc/ http://lists.w3.org/Archives/Public/public-ortc/. In addition to using JavaScript rather than a legacy format to configure the real-time protocols, ORTC addresses some useful real-world scenarios such as mixing and matching data connections.
