xiexe, silent, and apparently poiyomi do have an SSS implementation that's pretty similar. Also if you get the amplify shader editor [spoiler]from cgpeers[/spoiler] , its master node also has an SSS implementation.

Honestly, I've tried the SSS and for the most part it just ends up looking like rim lighting, if you turn it up far enough to notice. I didn't spend a lot of time with it though, it probably does improve the general lightness/feathering of shadows in lit scenes.
