First - this makes no sense to me in two different ways - the constraints proposal does not rely on a trusted environment. Second, we might mean different things by a trusted environment but I read this to say you are going to allow access to the camera with no user authorization. I seriously doubt this is what you mean so I suspect what we should be  talking about is what sort of trust we are is needed for a minimal implementation.

Really? more complex than what? This is the problem: many of us can not figure out what it is you want - all we know if you don't like anything that is proposed. So what is it exactly that you think this is more complex than. And what requirements do you think we need to meet - for example, most the people I have talked to think that we need to be able to indicate some hints about the desired resolution of image capture.
