Greetings. Before Brad and I found out about ISYS and OpenBSA, we planned on a collaboration with the developers of BlueBox (developed by dLoo Software and licensed under the LGPL): http://www.dloo.com/products/index.html I'm trying to get Nile Geisinger (head developer of BlueBox) on this list. In the meantime, I think you might want to take a close look at BlueBox. I believe OpenBSA, ISYS, and BlueBox have a great deal in common. Also, the thought has been brought up more than once (even with Nile) that Piper may be best used as a pipeline infrastructure for systems like BlueBox, OpenBSA, and ISYS, and that Piper should generally leave the user interface end of operations to those systems. I think this may be the working ground for DNP API specifications. Cheers. Jeff -- J.W.
