Dang, I used to play Project Entropia back in the day (way before the name change). I was hardcore addicted to the game...After spending like $1k on the game I decided I needed to move to something cheaper. And that's when I started playing WoW. Got overly addicted to that, then just had to make a clean break. Now I'm finding that I'm becoming just as addicted to PL...oh noes! Haha...

Anyway, I think the developers have already said that an auction house is on their list of "to do" enhancements.
