No. In fact, it is expected that in time, GridLAB-D will be supported by the collective contributions of users and developers without need for government funding.
The integration of existing technology is preferred, at least early on in the development of GridLAB-D. The objective of the open source project is to create the tools needed for conducting research, not to perform the research itself.
Contributors will be responsible for protecting their own intellectual property. Contributors are free to distribute modules they produce in whatever manner they deem appropriate. However, the open source project team reserves the right not to distribute as a part of the standard GridLAB-D distribution any code or module that is not licensed under a GridLAB-style license.
