Why is this post is in the NDS section? I originally had the idea for the DSi, but then thought it could work for both DSi and Wii. You know how in iTunes, when you purchase songs, videos, etc., you download a locked .mp4 that will only play on that computer? They also have a file-sharing thing where you can link several computers with iTunes and link them to the same account. This leads too not so many people pirating. Me and my friend gott a DSi and we bought games and we wanted too send the games too each other, but we couldn't. It really defeats the purpose of being able to copy games to your SD Card, because even though there is limited space on the DSi, it's not like you're going to buy every DSiWARE game there is. Its a waste of money. So maybe if Nintendo implemented this feature there wouldn't be as much pirating once the DSi Common Key is found.
