Thanks to Grimbert Jerome, AOI is likely to soon find its way into POV 3.7.

The attached image, rendered with an experimental version using 
Grimbert's code, shows a /single/ arrangement of two concentric spheres 
(reflected in three mirrors), using aoi to (a) create "windows" in the 
outer sphere that always face the observer, and (b) create the 
luminous-bulb-effect of the inner sphere by modulating the brghtness of 
a texture with ambient finish so that the sphere appears brighter where 
it faces the camera.

It looks prety interesting and cool.

Yes! AOI can be used for many things. Will we be able to specify custom points
of reference besides the default camera position?

Thanks to Grimbert, and to you for continuing POV's development!

Probably so - though it's not yet sure what syntax will be used for that 
functionality; it may actually end up as an extension to the slope 
pattern instead. I don't think it really fits with the actual AOI 
pattern: AOI doesn't just take the camera position as a reference point; 
instead, the ray itself serves as reference, making a big difference 
when looking at the object in a mirror; the slope pattern, on the other 
hand, is "static" in this sense.
