I did look around and found some GI python scripts, but those would do me no good in the long run, as they are not strictly Poser-Native.  Being that, they would most likely not work properly with the Poser Queue Manager for network render. They also seem to have a high crash rate and cause instability (especially with Point lights which I use a lot of).  While that would be nice for luminous surfaces, that is not strictly what I am trying for, I'm trying for more of a Halo or Color bleed that resembles the glow outline effect in Lightwave.  Additionally there are many reasons I would like to crack it as a shader node trick.  A big one is, if I can find the right combination of nodes to cause a surfaces color to "bleed" onto or effect adjacent surfaces, then it opens up a new world of effects possibilities (similar to surface effectors in Lightwave).  With some of the surfaces I wish for this to be done with, added geometry is too clunky, time consuming, or sometimes downright impractical to use for a haze/halo.  For the surface effector type trick - well - there is nothing for Poser like it yet.

Mainly, by generating an in-render effect, I can save much time in post processing effects.  This is especially useful given I do a lot of animation primarily. I had heard mentions of that Edge blend trick and what it described sounded a lot like what I was looking for - but could not find specifics myself.  Now that I have seen the effect firsthand (thanks again noxiart) I see that it is as described, and how I misconstrued it.  Still it is a handy trick to know, and I am glad I finally know the specific references.
