Could someone tell me about the legal and copyright issues involving the sale of pokemon and/or in game items for digital currency? This does NOT include the sale of pokemon/items for real money. Links to official ruling/citing would be great. If this is not illegal, what about the sale of hacked pokemon and/or items?

Ex. Selling a Shiny Pikachu for Neopoints (the currency in the petsite Neopets). This is not exactly the case, but you get the idea.

Thanks jslinder. Even not finding anything directly helps. It helps a lot if there is actually nothing there anyways. =]
