Well, it's funny, Viva is predominantly built on Drupal (which is open-source), though running D5. Then there is a heavy amount of customization on top of it, including hacking core. I inherited it 2 years ago when I came to work for Kiva and had to do a lot to get it to just stop breaking all the time. That said, actually two non-profits have asked to use it or have a similar functionality built for them, and I'm interested in doing something like that, but we'd have to de-couple all the Kiva specific stuff.
