Gitosis also takes like all of 5 minutes to set up and then you've got repositories that you can collaborate on and manage permissions between projects.

I set up our repo hosting using Gitosis a few years back and haven't had to think about it since. Accounts are also managed via a special repo so even that is done over git.

You could also put your collection of repositories on your Dropbox and clone from / push to there.

Gitolite is a better tool, with more options. It's easier to manage who gets access to what as well with gitolite.
