I believe it is coming. They trademarked a name for a trading 'company'. I forget what the name is. If will not ruin the game, it may grow it. In most MMos, you have the farmers, and the people who buy some of the stuff they just can't get it. In your example, you could list your item, and then see if someone is selling what you want. This will not break the game as many think because user data is not stored locally, it is stored on the server. This is not to say there is not an exploit to dupe items, but this is done with most if not all MMOs, so it is conquered technology. The biggest issue is what 'currency' would you use? Glimmer has limited value. Merits have a stupid small cap. Light and / or coins might work, but not sure.
