Hi Sean,

I mentioned to you some time ago that I can embed a ECJ 15 application  inside my Xholon open-source modeling tool. I'll try to download ECJ 16 soon and see if it still works. The integration is still at an early stage, but it is possible to use ECJ objects as nodes in the Xholon tree, it's main data structure. But it's not so much an extension to ECJ, as it is packaging too tools together in a peer relationship.
