I think that a panel about the differences between professional costumery and cosplay would be a really good educational experience. It seems like a lot of cosplayers think having a bunch of facebook likes is enough to launch their careers and something that really goes into the difference between hobby vs. pro would be really helpful.
Something about distressing and weathering costumes might also be cool. I could potentially even talk to people I go to school with about doing this...
