Actually, I misspoke when I said that IBL with AO was rendered obsolete with IDL... for "realistic" renders that might be the case but it depends on your artistic goals. You can create very powerful occlusion effects with IBL/AO much more so than with IDL, it has more controls to allow for such things whereas with IDL, AO is simply a present attribute without ways to really modulate it.

For instance I'll reach for IBL/AO if I want to do clay style model renders in Poser, it's very useful for that. I used IBL for these old renders of some models I made. You probably wouldn't know these were Poser renders unless it was pointed out...

Here's the thread with how to achieve the effect...
