Uh, I think the coded needed is a lot more than this and I am still waiting for an answer on what it is that you can do with JSEP's "more control"

Adam:
Cullen is right about that the JSEP example needs more code. E.g., this example do handle the case where one side adds several streams in a row, but it doesn't include code to handle glare (or any other special case that I didn't think of). I think we need to identify where it gives more control otherwise it's just a lot of steps that you have to perform in JavaScript in a certain order.

Yes - if you were implementing video on something like a iPhone, you would.
