I like this idea, although I think Nintendo is gong to have pirating already blocked out itself with the deadly SpotPass updates.

What'll be more interesting for hacking the 3DS is the fact that some AR device, when detected will in the future break the whole system. I think the way to do this is going to be an AR-type device for the DSi/DS lite that can fit 3DS games and copy their data and put it onto an SD card, allowing save file editing in a method similar to AC toolkit. Plus, save file editing in that method would be virtually undetectable.
