Here's an attempt I made a while back using the Multi Channel Mixer to get a more desirable SSS effect.

Basically I used a standard V4 shader tree in the first channel, and the same tree in the second, only with SSS and translucency turned on. For the blender, I made a gray-scale map to dictate where the second channel showed through. (Ears, nose, cheeks, etc.)

I don't think I even spent 20 minutes working on the setup, so I'd imagine things could be fine-tuned for much better results. Still, I like this a lot more than the wax-figure stuff I see coming out of Poser 9 :)
