Apple Thoughts: iPhone 3.0: Peer to Peer

Imagine local exchange of information over Bonjour and BlueTooth or WiFi from one iPhone to another. Now stop imagining. It's here. Apple has implemented Peer to Peer connectivity that will allow the exchange of data however the app would do so. Examples included business card applications, multiplayer gaming, etc. Apple seemed very big on this one, but I don't know how much it'll actually matter in the real world. It's more of a neat-to-have thing than a I-have-to-have-it thing, in my opinion.
