Um, how about anyone who has work buy their phone and signs a release that says they won't unlock it and flash a new ROM to it? That would include the VAST majority of large corporate customers whether they realize it or not. I sit 20 feet away from the folks who order the phones and 30 feet from the Exchange guys and our corporate policy actually stipulates termination if you do. They've let 3 people go for jailbreaking corporate iPhones.
