Given the wide array and the amazing development going on in the iPod Touch community right now especially utilizing the built-in wifi on the iPhone and the touch, I was wondering if there was a possible function of communicating directly with another iPod Touch... say in the vincinity. This would be a major feat to be able to directly send messages, files, media, etc. without connecting to a base station (router) or a computer. As many people know, wireless connectivity is one of the few features offered on Microsoft's Zune that the iPod Touch and the iPhone does not have. I would just like to see if something like this is theoretically possible (with the current hardware present in the iPod Touch and iPhone).
