POV's SSLT implementation does indeed work with radiosity, and by extension, HDR
lighting.

Maybe somebody more experienced with SSLT can help you. I've only been running
Lego tests in Blender + Cycles, and SSS comes cheap compared to POV-Ray.

Check out these two renderings:

Both were rendered in Cycles using beveling, SSS, radiosity, glossy (blurry)
reflections, and focal blur. (The render times were added to the file names.) As
you can see the SSS is barely noticeable, so maybe Trevor is right when he says
it may not be needed.

So perhaps the more important features you could be using are beveling, and
fresnel + glossy reflections.
