"is there much complex math involved?"
Much less for lights casting straight down than for lights casting at any angle. I think you could do it. No vector stuff or anything like that. Just scaling coordinates and checking to see if a coordinate is greater or less than an X or Z value.
Ps:
No email questions please. :-)
