I'm looking at GeoGit/GeoServer/OpenGeo Suite. It's all open source, but packaging OpenGeo Suite looks like a nightmare since it depends on Maven 2 and F20 only appears to have Maven 3. https://github.com/boundlessgeo/suite. I might try building GeoServer with Maven 3 just to see what happens. http://docs.geoserver.org/latest/en/developer/quickstart/index.html
gpstk recently published version 2.3. The jam build system was causing trouble in packaging and the Autotools implementation was broken. They now switched to CMake and it looks like we're going to make it this time.
