Idea of the Day : Universal Inventory Repository

Imagine if there was a tongue in cheek website that hosted your "universal game inventory". It would look very much like a typical rpg inventory list - with potions, weapons, trinkets, spells, etc. However it would be merged with web 2.0 ideas like having an open API, ajax calls for live updating, etc. You could have fun haggling over some silly sword with a friend, or send a "gift" of some crazy animated gif to a friend's inventory. ... HMMM.
