Why not both. Create a common model and use Core Animation to back the

I am considering this approach, and also re-looking
OK, so it looks as if I have found the answer to whether I would be able to use
layer backed views, and the answer is that even with layer backing turned on,
you can not guarantee the drawing order of overlapping sibling views:

CALayer has a 'zPosition' property which should allow you to set the order for
sibling layers.

Yes, that works if you are using pure CALayers - no problem there, but if you
are using layer backed views, it doesn't work - see
e.g. http://www.cocoabuilder.com/archive/cocoa/294950-problem-using-zposition-on-layer-backed-views.html
...so it still looks as if layer backed views are out...
