Well, the code itself can be made into a QR code and exported with the DSiware itself, and can be scanned by other DSis, as a way to share your work. No form of any kind of server is involved, you can even scan it successfully when the DSi is disconnected from the internet.Oh? Sounds convenient, however it probably required some form of server running in the background or internet connectivity seeing that QR codes don't store a lot of data. Still, it's a solution, at least.
