Hmm. I was under the impression UberPOV tries to unify all the different 
oversampling mechanisms so the sample count for the blurred rays already 
benefits from antialiasing/focal blur. But I might be mistaken.
I think the problem are those internal reflections that do happen with 
any object that is not just a reflective sphere. This seems to cause an 
exponential grow of the rendertime. I don't know enough of the inner 
working but MC-Pov (and all the other unbiased render engines out there) 
do not have this problem.
Anyway, let me know if you find ways to improve the render time with 
UberPOV, as I can't live without blurred reflections anymore.
