@Paul Lang, I do use the depth pass a lot. And, then let PS do the work. It's actually faster from a render time standpoint. But, the results are different than using KS DOF. So, sometimes I like that better. Not sure why you're saying you have to render twice. I just render PSD 16-bit and then check the Depth Pass box and it creates a PSD and a separate DP file. Am I missing something?
