This is EZSkin, a P9/PPro2012 python script that the author created for easy playing with SSS. It's free, the author is SnarlyGribbley, and he's a recent inhabitant of alt.binaries.3d.poser, and also of Smith-Micro Beta teams. I've been playing with it and getting surprisingly good results easily. It will NOT overwrite ANY files in your system or runtimes. It does create new shaders in the materials room. Not to disk though. Thought you might enjoy having a look at it!
