Planet Money @ NPR: A Man. A Van. A Surprising Business Plan. :

Everyone, it seemed, was facing the same problem he was. And this is when Adam Humphreys had his big idea. He called his buddy Steven Nelson. And they rented a van.
A large Penske cargo van.
And they parked it in front of the Chinese consulate. Right in front of the exit door, where frustrated visa applicants wandered out into the sunshine wondering what to do. These lost souls, like Adam a few days earlier, would now be greeted by a sign on the van: Lucky Dragon Mobile Visa Consultants.
Inside, Adam had tricked out the van to be a mobile solution to Chinese bureaucracy. There are a couple of Mac laptops and a printer, plus an old couch, Christmas lights and bamboo mats. It’s as cozy as a dorm room. And confused visa applicants line up outside.
