Invisible Networks DS

As the launch of Nintendo DS approaches, the rumor mills churn. Some are speculating that the WiFi capabilities of the DS will allow it to extend ad-hoc networks created by other DS units. Imagine distributed networks of Nintendo DS units spontaneously forming in close proximity. I'm hoping this is more than rumor. It would definitely further help distinguish the difference between the DS and the PSP (as if having a second screen wasn't enough). I seriously think that the Game Innovation Lab should try to get a hold of a development kit for these things. Anyone have any contacts in Redmond?
