This is a old test that I did some time ago in blender 2.37a, the goal wasn´t to fake SSS, but the results seems to be something like SSS but never working on it again.
Now after seeing in other forums some test about other fake SSS I decided to show what I`ve do, maybe you’ll find interesting 
and what do you think? is like SSS or not? the time to render each frame was about 8 seconds with internal renderer (blender of course).
It looks pretty good, what did you use?
did you map a cloud texture via ‘ref’ or ‘nor’ to ‘emit’ - ‘trans’ ?
and ramped energy?
Hmm…I could tell you if I could see the images.

It does look like SSS.
How did you do it?

I too would like to know how this was done.
Looks very good.

There is a blend posted at his blog.
fsss.blend

:o
Beautiful SSS!

I can’t download the fsss.blend file.
Looks good! the the black dots are a little odd, but other than that it looks real good. Can you post the .blend again your link seems to be bad
Hello everybody
Well… I don’t know exactly how it works… because I wanted to do another things and that was the result, some kind of fake sss
The procedure is to make a dome light (with negative light), and make a material like in the example (http://salvador.mata.com.mx/Fsss3.rar) and press the render button… and if you want you can place a point light over there.
Check the file/materials/light for more info about it, I hope you can find it usable
