photon emit radius for vray light

[super gnu]

so we can put those caustics just where we want em.

would probably mean the vray light would need a (potentially confusing) target.

You might get away with a spot light that only produces caustics.

of course.. theres always tricks... i was just using the vraysun and though how nice the photon radius setting was.

Yes, one can probably figure out something similar for other lights, but it's more complicated, as they are not directional, like the sun.
