On my initial tries, I also ran into a few issues with Sparkleshare, but I haven't given it too much time so far.

Nice to hear.

That was my main reason for taking Python: rapid prototyping with mature libraries (pyinotify just rocks, e.g. compared to the JNI inotify wrapper).

Thanks - I will try to merge this tonight/tomorrow, as soon as I have wrapped my head around the gitorious merge request interface.

Excellent. I am open to many changes/improvements in this little project.

That's basically it. Then you start the script and it should be working for monitoring local changes and automatically committing them. For synchronization with other instances, you will also need to configure an XMPP account to use for this purpose.

You're right. I've never actually tried it on a completely empty repository. We should either document this in README (the setup process) or make the script realize when there is no master branch and do a "git push origin master" in this case. I will need to dig into the git remote command a bit more to see what the best option is here (I don't like parsing the output if I can avoid it).
