Looking for a charity for CodePlex project owners to donate advertisement revenue

One of the things we’ve been planning to do with The Lounge as our new advertisement provider is to allow project owners with a single click to opt in to have their advertisement revenue go to charity. We believe that pooling individual projects together would provide a nice charitable donation.

However, we haven’t been able to finalize on a charity yet. We’re thinking maybe a non-profit that’s focused on Open Source or education in IT? But maybe people would prefer a charity like Habitat for Humanity? We wanted to get your input what charities come to mind that we should check out.
