Thought the impending Nintendo DS was simply a Game Boy with go-faster stripes? Think again - this baby could herald in a wireless revolution! Or something. Engadget reports that the DS could be used as wireless navigational device. By doubling up as a repeater hub to link to other DS's nearby, gamers could form spontaneous networks without the need to be near a traditional access point. This is all speculation of course, but don't bet against Nintendo pulling something similar out of their Mario adorned bag.
