I don't think you need this to store devices you've seen before.

But on the others, it seems to me this would work really well in 
unconstrained cases, not so well in constrained ones.

It does NOT solve:
- don't put up a self-view if you don't meet minimum camera requirements.
- hide device-choice functions in the UI if only one camera meets 
requirements.
