This is really cool!  I imagine the pilot program is a success because lots of kids (and some adults too — including myself) have the Nintendo DS or DS Lite device.  This kind of application really shows the power of having a small wireless entertainment device.  An added advantage to DS and DS Lite proliferation is the cost, which is around $129, which is pretty cheap for a hand held wireless device.  I think it would be neat to have more interactivity like this in other places besides the baseball field, like theme parks and museums.  Can you imagine having additional information about an exhibit available to you or your child through their DS?  They could take the info home via the DS.  Or maybe content specific gaming (aka targeted ads) at various attractions — like a maybe a theme park ride sponsor’s mini-game or “entertainment” available while waiting in que for the ride.
