Inspired by your request I tried it myself. I faked the reflections 
using cylindrical lights. The directions and positions were calculated
by povray. Since there aren't any other objects in the scene between
the light source(s) and the disco ball, it was easy to test whether or
not the disco ball blocks the light path.

I have posted the image in povray.binaries.pictures as well as the source
code. Be aware that the image needed 73.5 hours to finish on my Pentium 150.
Perhaps I will add some nice back scenary and animate it, if I have enough
time...
