yeah, I was actually hoping for a more automated process... wishfull
thinking I guess? Like optimally, if there were 4 machines each would render
every fourth line and the image would get written on one of the machines..
so kind of like multithreading. I was wanting it also for single images not
animations even.

AFAIK there are a lot of practical problems with this approach -
anti-aliasing and radiosity in particular. A better option would be to
render larger areas with overlap between perhaps?

With antialiasing the problem disappears by just rendering larger areas
(one line per process is a real killer with antialiasing, but if you render
several tens of lines in a bunch then the antialiasing overhead doesn't hit
so hard).
For radiosity there's no yet any perfect solution.

Have you tried PVM-Pov? (see Ken's reply for the link)
PVM-Pov distributes the rendering of the image among the number of machines and
you get the whole image on the machine where you started the main process. It
works even fine with anti-aliasing; radosity is not perfect though.
