When you say IBL sphere, what ar you referring to? Did you put a shader on a sphere, or are you using true IBL in the render global settings? If it's just a textured sphere, then you should haev no problem doing this with render layers, and setting layer overrides for the reflections.
I was using a sphere that emits photons, but now I've switched to the in-built IBL functionality, and I'm getting much better results.
Theres still something I need to figure out though, and thats how to get a 'reflection mask'. I'll have a search in the forum archives, see if its been brought up before.
And might I just say, Dann, you are god.
EDIT: Cant find anything about render masks..
I just need to produce a black and white image that displays where a reflection is for use in compositing software.
