In CS5 at leastyou can achieve this effect:
by painting the mirror 100% black (preferably not sloppily),
adding a layer mask to the mirror layer, showing everything outside/behind the mirror.
Now you import the two layers you want to use, placing them like this:
Note that the two top layers are set to be 'clipping masks'.
Finally, select the mirror layer and click the fx button on the layers palette, clicking 'Blending options'.
Then change 'Knockout' to deep, and the left handle of 'Blend if' for 'This layer' to something 2-ish.
Now you can move the mirror layer, revealing the flanbase below...
If you want to look at the psd, it's right here.
