I'm preparing a short talk for a conference in august and I'm looking for open source projects that are using agile methods internally or have tried them in the past.

My goal is to talk about the things that work well and what won't work and promote the agile methods a little bit, because I think certain agile techniques are a good fit, but don't seem to be that common in real development.

So does anyone know projects that have tried agile methods and techniques before? I'd like to contact them for a few questions.
