Maybe a way to only reorient around a specific axis? That way, you could 
use a rectangular area light with the reorient feature set to the axis 
of the desired cylinder. From a point within the scene, it would look 
pretty close to being a cylinder, you most likely couldn't tell the 
difference without the aid of a computer program to compare images.

Spherical sources can already be simulated with the existing reorient 
patch and the circular area light patch.

These could also be done with high-ambient textures on illuminated 
objects and MegaPOV radiosity, using the radiosity for the lighting...
