Would a math trade be allowed, and if so, is there interest from other players in doing so? I've done a few at other conventions, and the process usually takes about 20-30 minutes, and needs a medium sized meeting area (2-3 3x6 tables).

For those unfamiliar with the term, a math trade is where participants list games they would like to trade, choose games they are interested in from other's lists, and a computer calculates the highest number of trades. You often give a game to player B, and get a game from player C, since the program can optimize the number of trades with multiple participants.
