I have already started a message stream with the CarMan project. My project is more toward logging, not display, so the "engine" is more important than the "body". In fact I've altered the program and wrote example programs SPECIFICALLY so that it would be fast and easy to integrate into Carman, but Carman itself is larger and more complex, though I think minigpsd/miniobd2d would simplify it a great deal.

My code is GPLv3 - they are welcome to use it. But I am still working on the OBD2 communication core.
