BMORG has a special ride share site rideshare.burningman.com, why not set up a similar board for aftermarket ticket sales, aftermarket.burningman.com? Even before this historic sell out, people have always been buying and selling tickets because of unforeseen circumstances.
The rules could be tickets must be sold at face value, or maybe even 10% over face value (some people probably buy their tickets on credit cards and are paying interest all that time). I'm sure if this is thought through and implemented properly is would help to cut down on scalpers, help provide a safer place to buy and sell (tickets could be verified automatically at the time of listing), and most importantly, IT WOULD KEEP THAT TRAFFIC OFF OF EPLAYA!
