Smooth subdivision is well implemented in SU, but how to subdivide the mesh on a organized manner, without pushing or modifying the mesh. The test on the image is done in 3d studio max, is a simple and common tool to add extra geometry. Notice some shading differences in the radiosity levels from both models.

Is there a way to use this concept to subdivide the mesh without making it spherical, simply remove the tension that pushes the mesh as a sphere. This will help when calculating radiosity in Renderlights, a simple room with subdivided mesh will just look much better on the radiosity engine.
