Hi everyone,
I wanted to keep my save games synchronized between my computers, but KSP does not use Steam cloud and I didn't know of any other tool that does that already.
So, I wrote a simple wrapper script to use Git (http://git-scm.com) as a save game synchronization mechanism: it does git pull origin master before starting the game to get the latest save games, and git add * && git commit -m "$(date)" && git push origin master after the game completes.
I've tested it on Windows and Linux, and as long as you have git in your path it should be fine. It will probably work on OSX as well.
If you like the idea, please try it by forking the repository there: https://github.com/kerpak/KerbalSyncProgram. It's on github but there is no limitation about where you will push your save games: it can be any git repository, hosted wherever you like including private repositories if privacy matters. You just have to configure the origin remote url correctly.
Also, please note that although it could be used to synchronize the plugins in GameData, the folder is currently excluded in order to avoid synchronizing large files, or copyrighted material, but you can get rid of the limitation by allowing the GameData folder in .gitignore.
