Laminar Research open source all their scenery tools for X-Plane. I believe IPACS should consider doing the same to encourage community development projects.
If Geoconvert was open source under GPL or MIT I could bundle a custom build with AeroScenery and make the end-to-end experience seamless.
Secondly, in my work writing AeroScenery I'm finding Geoconvert a pretty frustrating tool to deal with. It will happily tell you that the run was successful, but no output is generated and the logs give no clue as to why. If the tool was open source I'd have hung a debugger on it and stepped through the code by now
