Mrs bosbiz and I used it for the first time yesterday, returning from Munich.

First impressions:
* clearly marked, wide open kiosks.
* took some time to find which airport we were coming in from -- listed differently, not under Munich or MUC.
* thought it was long, until we realized we were the first through immigration, even though we took our time getting off the plane
* separate entrace to customs for program, shared with crew
* agent stopped us and said we were in wrong exit, showed our printout and she said "oh ok, you weren't in uniform". Asked her what she meant, she admitted she was confused and all was well.

All in all a good experience, despite small hiccups. Time to exit from walking off jetbridge - 14 minutes, with priority-tagged bags that came off the plane first.
