The first details of the new Live services, which will be a compulsory part of Xbox 2 games, were revealed by Microsoft VP J Allard at the Game Developers Conference last week, with one of the most notable updates being a micro-payments system that would allow companies to sell small pieces of add-on content for their games, such as skins, vehicle mods or maps.

Now OXM is reporting that this functionality may be extended to users as well as companies - allowing players to create and trade their own in-game items, although presumably the game would have to provide some creative tools for this to be possible in the first place, so we wouldn't expect it to be a feature of every title.
