Very cool. I'm a DL4J fan. I actually did a talk at Tri-JUG a couple of weeks ago, on real-time machine learning and BPM, which featured DL4J as part of the tech stack. I'm also working on a SaaS offering around AI/ML and plan to include support for DL4J at some point. Hopefully at some point I can get to a place where I can make some useful contributions to the project.
