Re: Tracks in multiple Stream …. Re: Teasing apart the data API questions

Sure, that all makes sense along with the examples you and Harald raised but I should have been more precise in my original email. I'm talking about in the context of a single PeerConenction objects. In all these example there would still only need to be one of theses media streams added to a given PeerConenction object. So, I'm still at the same place of not seeing why we need this that I was when I started this thread...
