@Chris If it's an Auction House, that's the end of half of the fun of Shroud. Running stores will be finished. Market towns will be finished. Even if there's a fee, that's it for the trade part of the game, all merchants might as well head back to Eve. It will also be devastating to the housing system, as having a vendor is one of the big reasons to own a home. If it's a global directory, no worries. But I would suggest focusing on the last 20% of existing systems first. There is a lot of trading that is NOT happening because the vendors don't support it. Partial stacks. Components in the buy order tree. If an Auction House is made so you never improve vendors, well, you get what you pay for I guess. That will be a bland WoW style economy.
