I'll make a V6 version of AO (with the end-userified gui we did with Arjo) once I get the time. I was supposed to do it last weekend but I've been too busy (sorry Jyrki). What comes to the speed issue, the V5 version is indeed as slow if not even slower than one bounce GI. The V6 version should be significantly faster as it doesn't do unneeded target surface material evaluations. The Arnold renders used GI, no AO there.
