With the (very recent) release of the first (GP)GPU supporting both
64-bit floats and recursion, adapting POV-Ray for (those) GPUs might
actually become technically feasible soon (though it still may take
quite some time before it hits the dev team's top priorities list).
An open question would still be that of performance, which will mainly
depend on how well the software architecture fits with the "Extreme
SIMD" ("Single Instruction Multiple Data") hardware architecture. We
might see a positive surprise there, though it could just as well turn
out a big disappointment.
In any case I think the easiest-to-implement approach (and hence the
best approach for official POV-Ray) at GPU support would be to implement
network rendering first (it's high up on the ToDo list anyway), and then
treat the GPU as a separate rendering node.
