New to git

Hi, I'm considering to use git to track my sources. So far I was able to use git on a single machine and play with its basic features.

Now I would like to setup a repository on a server and use it as a central point of distribution for a few other computers. As far as I can understand, the default mechanism for push / pull requires that git is installed on every machine, including the server.

My problem is that I can hardly install git on the server for several reasons that I will not explain here (also I'm not the administrator of the server). So I am looking for other solutions.

For the moment I came only to the following idea: mount the remote repository via fuse-ssh and use the local installation of git to push / pull changes. Surely it is inefficient but I don't care too much (my repositories are small enough I think). Can you see other drawbacks of this solution?

Also I wonder if other kind of synchronizations are possible (rsync, unison, ...).

Are there other obvious solutions that I'm missing?

Thanks, Marco
