Because I would have to disagree with that. I think we could very easily support such uses cases with rather minor changes to the API. In fact, the proposal I made for adding just 3 methods (the NoPlan JS API) allows for either Plan A or Plan B (or even Jingle, mostly), which would make things a lot easier for such use cases. Now, my design might not be the optimal. Perhaps we could do better. But I think it is possible to serve all these uses cases with a pleasant API. > > > > > > > Along with that, is "use Jingle for signalling" included in your set > > of "most of the use cases"? > > > > > > No, I don't think it is, since it's not SDP. > > > > Maybe I could phrase this differently: It was my understanding that you > > should have > > API points to get the PC to emit SDP that would express the policies, > > preferences, > > actions, etc. that the application wants.
