I think it's an awesome idea, but I also believe it would be more trouble than it's worth. I'm not sure exactly how eBay maintains control over all the users, buyers and sellers on the site, but I do know that EoFF probably does not have the legal means to mediate that sort of trade. But this is something I'm just ignorant about.

Also, we have no way to enforce fair transaction, as far as I know. What if one member sends payment to another via paypal and never receives the item they purchased? How do we handle that?
