Of course it would have a auction npc every place that Ferengi can access.
and take 10% for the referring auction consortium (FAC for short

and maybe a Ferengi doff or boff could reduce this to 5% or have other relations with the Ferengi deals.
The Ferengi FAC msg me they are tired of the exchange system were stuff keeps going lower and lower (that's blasphemy to Ferengi!!!!)
The FAC is about getting more and more for your items not less and less!!
(no warranties all rights never implied)
They feel this would be a great idea for increasing our space economy. of course your item would be returned if not sold but this would be a rare circumstance now wouldn't considering how well Ferengi know how to sell stuff!!!

This could be used for Casinos and pleasure houses as well. Imagine a Ferengi who bought himself a Vo'Quv and the refit it, to be a giant traveling resort, with Dabo, and Tongo tables. As well as Holosuites, and the Auction house inside. When people are invited to your ship you'd have to cover all bets on the Gaming tables and operate it like any Casino. Well any Ferengi Casino.
