My macro only does reflected caustics and requires the Superpatch;  it also
treats all light sources as point lights, so I doubt it'll help you. Sorry.
There are very few renderers around that do the thing you want and POV
currently isn't one of them. You might try out BMRT (Blue Moon Rendering
Tools); it can handle caustics to some extent and is freely downloadable.
But unless you are somewhat familiar with the RIB format and shaders, (and
have a Cray or sth., because caustics are slooooow), I suspect this is of no
use, either.
Wish I could help more.
