Could an Open Source movement network be established between schools?

For a couple of years I have been looking for a situation where my students find interest and inspiration in some authentic real-world-related problem while learning programming. The subject is abstract and the pupils are many times lost with a question of why and wherefore.
Therefore I try to create an environment with a customer (from industry or school) to sharpen the situation and the learning outcome. This comeing semester I will do this in a different way.

My ambition is to create a situation where pupils are customer to pupils and where we are constructing "interfaces" between different groups of pupils. All to make it easier to communicate process of learning between groups. Is there anybody else that have done something similar?

Would you like to be involved in collaborative learning in programming?
