So, with all this talk people going outside the market.. Where's the security? What can I do MORE to help?

What if I made a 'middle man' upgrade.. That is, when someone uses a middle man (I will only make middle men on a select few), that person would hold XYZ item until he has both pieces, then distribute the rest.

He can do this for a fee.. Points, a small % of the trade, etc...

Where does it get sticky? When you guys start using paypal.. There isn't a good answer for that (yet) but I am working on it
