I think a computer-themed after-school care program plus summer camps is a good idea. As another poster mentioned, however, you would end up with the problem of teaching a bunch of kids that are only there because their parents work and need day care. My daughter is going through this right now. She is in an electronics camp for the week. On the plus side the counselors love her because she is one of the only kids in the class that pay attention. On the downside, she is one of the only people in the class that pay attention.

Alternatively, I've heard of franchises that market to existing daycares to come in once a week to do computer classes, charging the parents a nominal fee per session.

I'm very interested in hearing other people's ideas, this is something I've looked into and would be interested in doing as well.
