Mirror across sphere rig

In my previous post I explained the math and maya nodes you need to create mirroring of positions in 3D space. Here is a different, more complicated, example where I created a rig that mirrors across any point on a sphere. I used a sphere but it can be any object you want. The only limitation would be a low poly mesh where the mirrored positions would snap since there would not be enough polygons that would provide data on normals that would ensure a smooth transition. In that case I would probably add some nurbs patches that match the poly shape and use their normals.
