Actually, I was looking into this last night. I have some basic pov code -
but be warned, it DOES NOT work properly.  depending on the values, it only
shows quarter of a torus, due to degenerate triangles. (warning! do NOT put
spheres at the vertices for values that give you degen. triangles. That's a
REALLY good way to lock up Pov. )

The code that I have is here: http://24.108.7.134/supertoroid.pov

Also, looking into the pov code, the torii that are used in pov are actually
4th order polys, so modifying that isn't as easy as you would think.

I even thought of adding another keyword to the torus code.....
