My sons school already has a robotics program using Lego mind storms. The kids love it. He's 6, and was allowed into the program early due to being adept at lego and strong in maths.

It's a public school. In the big scheme of things, a couple of mindstorms kits are not that expensive, the trick is finding teachers who are willing to go the extra mile and run these types of program's.

Still, I think this is a great idea.
