I did some work a few years back for a company whose entire business model was managing the rules, licensing, payments, and paperwork for interstate alcoholic beverage distributors. It was an eye-opener. The code itself was a horrifying pile of special cases, largely because each state had its own form, which required its own set of information, and its own rules regarding shipments, and its own license fees ... I wouldn't be surprised if 20% of the retail cost of alcoholic beverages is due to the headaches associated with moving them across state lines.
