Surplus ICT capacity as a source of revenue?

Ewan , in his recent interview on Mediasnackers , talked about school students teaching IT skills in their communities.

Yesterday Grid Today (!) with Grids for Kids by Tom Gibbs went a step further:

"Companies and local economies that need to bootstrap their workers and citizens into the global collaborative world can share their local education grids as a way to share both the wealth and the expense."

There's certainly a lot of unused processing power in schools, especially outside the school day. If this is a potential source of revenue, we need to explore that possibility. New fast networks will make it more practicable.. even if that wasn't their initial purpose!
