Interesting concept on game distribution

Over at Mac OS Rumors site, there is an article about the possibilities of the iPod as a cell phone and game platform. It discusses an "iTunes Game Store" as a possible outcome of this. This would be excellent if it actually comes to life. What a great distribution model for games created with Unity. However, as always when dealing with speculation and rumors, keep reality in check. What are your thoughts on this idea of distribution? Would you participate if allowed?[/url]
