Well, fazzbazz.  Rosity, I hate your time limits and your response editor.  Hate to bite the hand that feeds me, but it's the truth.  :(

A couple of errors in the above.  Spanki, I noticed your explanation about concave polys, after I posted.  Presumably there can't be concave tris?  Or could those normals still point backwards, tris or no?  Hmm.  If tris can't be concave, the error I encountered has another cause, because I was working with our triangles.

*"I'm going to look at a couple of additional screening methods, too."

"Screening"  in the above should read "smoothing".

Cage had some freebies, compatible with Poser 11 and below.  His Python scripts were saved at archive.org, along with the rest of the Morphography site, where they were hosted.
