Yee-ha! Flamenco, the leading faceted browsing research platform, has officially gone open source. See also: Flamenco section at SourceForge.

I was lucky enough to get a preview copy of the code to test out a few months ago. It was easy to install and within a few hours I had learned just enough Python to make changes. I plan on using it for some of my personal sites - perhaps reviving Usable Web on Flamenco, if I ever get the time.
