I do know that good subsurface scattering can help an image greatly but I also know that until about a year or so ago, Maya was without a true SSS system and you had to work out complex shader trees yourself. The fact Poser's following along in a similar way is pretty cool I think, even if it's not perfect...but again, I'm a modeler and rarely do I have the time for proper renders of full scenes...my modeling itch starts up when I try.

Also keep in mind I am clueless when it comes to this stuff, and I'm sure using a map to tell the computer where and by how much to use the effect would help. These shaders all had translucency along with the simple Fast Scatter. I'm not sure if that's a good thing or a bad thing but they did. They also had it set a bit higher (I think 0.5 in some cases) then the default setting of 0.2.  

Here are the same shaders with raytraced lights.
