"The innovative program is called the Nintendo Fan Network. For a fee, the network uploads a program onto the user's DS Lite and allows fans to order food and drinks, watch the live television feed of the game, access stats and scores and play trivia, all from the comfort of their seat -- whether it's a premium seat behind home plate or in the top row of the stadium."

This is a very cool example of how Nintendo is integrating their consoles into our lives.

I'd come up with an actual cartridge, too, something that would let you track stats yourself, swap virtual cards, even compete in a fantasy league. A signature book would be awesome, but I'm wondering how the players would react to digitizing that aspect of fandom.

There are all sorts of cool possibilities. Maybe even the ability to post messages to the Jumbotron (I'm assuming they'd employ a human filter to check for the naughty stuff).

Makes me almost want to go to a baseball game. If I got bored I could always pop in Pokemon.
