Last year I was thinking about creating a service for this built on top of Hubot. The core idea is that you would go to a website and configure your profile. When you get a new Mac, you would just ssh install your profile, go way, come back and your Mac would be setup (Similar to GitHub's new employee setup). I didn't do much research into whether or not anyone would pay for the service or how many users they might be. But it sounds like this is a stab at helping individual users set up something personal.
