Dude, you're talking like JFK or anyone else would actually try to make money from a picture of you or any model you brought with you. When would that happen? As far as I know, JFK's website and magazine are free and I don't know of any other commercial photographers that go to the shows. Oh, the guy from Klixxx is usually there running around but they don't make money from the show pics either.

You simply sign the release so the show promoters can use pics that are taken at the show to promote the show next year and not have to worry that if Rhetorical happens to be in one that they have to get his permission.
