Looks like the Line Rider developers are looking to add some value to Wii and DS versions of the game:

Many questions arose when inExile announced it was bringing the custom obstacle course game Line Rider to the Wii and Nintendo DS. But at least one of those questions has been answered: players will be able to upload and share their course creations onto the official Line Rider Website.

Sounds pretty cool, and I like that they’re sticking to the formula in the flash version of the game.
