I think photons wouldn't work either :-(

For POV-Ray 3.5 we will at least have a list of all the global variables and
in which function(s) they are used.  It is surprising, there are even
globals that are used to just pass an argument from one function to another.
While about 80% of the global variables in POV-Ray could be removed in short
period of time, at least 20% would be next to impossible remove.
That is one of the reasons why there will be some kind of rewrite for
POV-Ray 4.0.

One of the long planned goals surely is to offer multithreading and network
rendering, but this will surely not happen before POV-Ray 4.0 :-(
