I think the easy way for Fanime to handle this situation is simple....just sell the exhibit space, just like every other convention. After all the artist is liable for something that is copyrighted or bootlegged, not Fanime. A lot of artist alleys and dealer's halls are really starting to get in the individual's business about what they sell and such. I do not think anyone should be able to tell any artist wether or not what they sell (custom buttons, plushes, keychains, etc.) unless they are the license holder, or have direct proof that what the artist is selling is a bootleg or replica/licensed item. I have several friends who sell buttons and plushes, totally their own patterns and designs, but based on licensed characters, that because they are fanart, are not permitted to sell in the AA. Why doesn't Fanime just sell the tables as exhibit spaces (which is what they are selling to artists after all), and just make very straight forward clear cut rules about what can and can not be sold? Attendees love buying fanart in artist alleys too.
