I moved it to
http://www.github.com/windhoverlabs/sage. It's part of a larger project at
http://www.github.com/windhoverlabs/ardronecfs, but it will be a couple weeks before I have everything posted. I'm still playing with the YAMCS deployment scripts. I currently have it setup to deploy locally rather than install system wide in an /opt or /usr/local directory. That's because I intend to use YAMCS primarily during flight software development, possibly in parallel with multiple developers. So I view it as just another development tool like Eclipse CDT. Though I would like to convert my web client system to use YAMCS on the backend so I can use it for testing and operations too.
Once I can load YAMCS as a plugin, I have my own plugins including a live video display with heads up display overlay, and gamepad controls for manual flight.
I would also like to use YAMCS on a couple other projects. I'll post those when I know more.
