Thanks! We basically open-source everything we do; the problem is committing the resources to support stuff and polish it into a usable product, which unfortunately doesn't always happen.
We haven't been polishing the JOL/BoomFS work, because we're currently working on a brand-new language ("Bloom") that should be much more programmer-friendly; as part of that, I'm writing an efficient C-based dataflow engine. If you have any more questions, feel free to drop me an email.
The Java-based implementation can be found here: https://svn.declarativity.com/lincoln/java/trunk/ . The old C++ implementation (P2) is https://svn.declarativity.com/p2/trunk/ .
