Hi will,

Already wrote a (quite powerful) analysis tool from VXLSE.
See http://www.vdsp.myweb.nl/vxlse.zip
Under the Auto-normals menu, there is a "Normal report" tool.
It contains my auto-normals implementation, and can identify between 64 'directions' (not really, just the 6 sides of a box actually).
You can specify a mode shown in the upper chart first.

If someone does the boring job of trying out all modes with a lot of correct *TS* voxels, it's a 5-min job to create a auto-normals function out of it.
Yours could be better of course.
