I actually think the EQ2 economic system was the best, at least at first (they of course screwed it up).
Tie your broker in to your house. Make your house your shopfront. People can either buy through the AH (at a mark-up) or go to your house and get it at cost. Not only does it allow people really interested in it a way to work the system, it also makes houses more "important" and gets people to see that content.
And frankly, EQ2's housing was pretty badass. You just never got to see a lot of it because they took out the impetus to visit other people's homes (other than just visiting).
