Yes.

This sounds interesting...the only method I know of is to use completely 
transparent hollow shapes to force new intervals, is this what you are 
talking about or are you thinking of a better method?

Yes.

It isn't physically correct, but I still know how to do it.

Yes. I'm even working on a program to create the necessary files, and 
automatically generate the POV code.

I think you need to define "desired text effect". I assume you are 
referring to the circle text macro, but that could also describe using 
multiple objects to get text of different sizes, or any time you use 
multiple text objects.

Hmm...
You know how to make an arbitrary warp (such as the displace warp, 
uneven scaling, or twisting) of any pattern in POV script.
You know how to directly specify the rgb color of pigment/media using 
functions.
