I Had not thought about plugins because all the devices are identical in capabilities. The devices are complex cameras. I wanted to have each cameras have it document window to display the specific video feed, but a single palette to control the brightness/zoom of the frontmost window/camera. This is an over simplification because in reality, each camera has lots of controls and status. If each camera/device has its own exclusive gui element, the screen will be cluttered beyond acceptable. I was modeling my solution around something like Photoshop or Illustrator where multiple documents use the same set of palettes.
What you're saying is that you have many cameras, but want to control one at a time. You are using the active window (or document) as a selection mechanism to choose which camera to control.
Seems to me that if you want one camera per window, you'd want the controls for that camera in that window, though I see what you're saying about having too many controls. Maybe it's the selection mechanism that needs more thought? You could have a single window with a list of cameras and you select one to control. Then it becomes more like a master-detail interface which would be probably more manageable.
If you do want to stick to one window per camera and have the controls apply to the from window, you can use notifications to listen for window activate/deactivate notifications and track down the related camera via the window's controller, which would be a class you developed.
