We've been assuming that the typical implementation of GetUserMedia 
would be to show the user all the cameras -- preferably with a preview 
of each if possible, though lower resolution and perhaps low frame rate, 
or if that's infeasible just a list and a preview pane -- and let them 
choose.  (Similar for audio, though with a different mechanism for 
preview.)  The hint could control which is the defaulted selection.
