Handwriting recognition coming to the DS

Nintendo has announced a deal with Zi corporation to license Decuma technology for the DS. This should allow DS owners to write naturally using the stylus and touch screen. How does Nintendo plan to use this in the future is unknown. Some possiblities are bringing Brain Training titles over to the US or the start of PDA software for the DS. Or maybe some company is thinking they can create a game where players have to scribe the script of the Doom movie as fast as possible to avoid attacks by flame spewing demons.
