cool... having an interaction map when you visit theme parks is definitely a nice thing. we definitely have the technology to do it, just not the hardware and software. the DS, with its intuitive input interface, is perfect for this sort of application.
i hope this catches on in a few years; and in addition to just being tour guide, it also shows traffic (as in queues) real-time so tourists can decide which attractions to visit and which ones to avoid. that would require WiFi, which is catching on a lot slower than i had been hoping for.
what nintendo should do is partner with them, and have DS rentals or something like that. maybe for $9.99 a day, including headsets. if i don't have my DS, i would totally rent one. in fact, for $9.99, even if i have my DS i would probably still rent one.
the Wii is an epidemic.
