GPS attachment for the Game Boy Advance

The big E3 video game expo is this week, and besides everyone waiting with bated breath for the official unveilings of the Nintendo DS and the PlayStation Portable, the first few announcements are starting to dribble out, like this one about a GPS navigation attachment for the Game Boy Advance from RedSky Mobile. Besides being able to tell you where you are, there are also plans for multi-player games that take advantage of the GPS, though it doesn't sound like any are actually in the works yet.
