  The lightmaps used in real-time rendering engines are precalculated
usually with the so-called hemicube algorithm (use google for more info).
The great thing about this algorithm is that it can be used with hardware
(ie. the 3D-card), which accelerates the calculation of the lightmaps
a lot faster.
  Naturally the same job could be done with POV-Ray. The problem would
be that while a 3D-card renders at least a hundred of lightpatches per
second, it would take POV-Ray at least some seconds, if not minutes
(depending on scene complexity) to do one lightpatch.

  Thus, it would be possible, but not very feasible.

  (By the way, with POV-Ray the hemisphere algorithm could be used, which
is the "original" algorithm used by radiosity. The hemicube algorithm is a
variant developed so that 3D-cards could be used for the calculations.
However, the differences are so minimal that there isn't really any
advantage of this fact.)
