Go ahead and e-mail me the code(or upload it to one of the groups here),
and I will try it out.

It may be strange (and yes, I'm talking about these 2 renders) but I can see
how the word "cartoon" isn't completely accurate for describing this effect.
From what I've seen so far this process wouldn't be totally confined to that
realm with certain artist skills at the controls.
I know, I'm sounding like I don't like cartoons or something; sorry, never
meant that to be.

Are you saying that this could be used for other types of images, such as
drawings, like CAD kinda stuff?

Shouldn't that have been taken care of by the normal edge detection?

I would suggest this. Instead of having a 'hard' thershold, have a 'soft'
one, probably with a linear falloff over a user-specified range.
