The Screen Saver Engine will create two instances of your NSView, one for each screen (except when clicking "Test" in System Preferences). Why not just change your code to allow specifying different settings for each screen? You can find out what screens are available by enumerating over the NSScreens and, when loading a preference, appending the screen's number to each preference key. Or even just to the domain and explicitly specifying the domain whenever you load a preference. When a view is created, you can ask its window for its screen in -viewWillMoveToWindow: and load your preferences appropriately. I think in the long run, this will not only be the faster approach, it will also be much more elegant. You can provide a decent UI to your users (maybe with a popup menu to select what screen to configure for).
