The easiest approach would be to apply higher AA to objects that the 
rays hit first. I don't think there would be any need for "2nd or more 
generation" object specific AA. So if the ray hits a transparent object 
with higher AA, then we would AA only that specific point no matter what 
objects there are behind (with whatever AA settings). Basically this is 
same as 2D AA map based on regions - I think?

And I don't think this is misusing AA when aiming for blurred 
reflections. I think down scaled normals IS more like a real world 
approximation of blurred reflections. AA simply tries to outcome the 
resolution (and eye) limitations in that situation. Isn't that the 
purpose of AA?
