They really need to think through your business plan here. How do they plan to make money? They can't really go ahead and charge customers for the service (illegal in most states?). Also, how do you solve the synchronicity issue? If I'm at Gate 7 and you're at Gate 22, are we going to chat and then meet up? At the Starbucks or the rest rooms? And are they serious about the sex, or is this just a ploy to make a mobile dating website? There are some serious questions they need to think about before going any further with this idea. Just my 2¢
