I was just feeling nostalgic for OpenCM, an early cryptographic-naming configuration management (version control) system from Jon Shapiro's EROS group at Johns Hopkins. I think Jack Lloyd (later participant on Monotone and author of the Botan cryptographic library) was one of the primary developers, if memory serves. It was the first VCS that I used that had competent branching and merging and really felt comfortable for parallel development. Sadly it's dead and gone, now.
