You might check with the volunteers who have run the welcoming committee at the Reno airport - airplayainfo(at)burningman(dot)com . They would know the numbers and logistics. People have to pick up water and food and stuff, so how to work that enters the equation. Might be a good idea to start planning for 2013. You would also need a vendor permit and a lot of coordination with the ORG, and they are starting to get very busy. Good idea though!
