autopilot

So I was reading about a module today called autopilot (http://www.workhabit.org/change-management-and-drupal-autopilot-news) and was wondering if anyone here is involved or knows anything about it and what sort of differences/similarities there are between it and Hostmaster2.

I'm very interested in the topic of change management and and such things, but just getting my mind wrapped around these tools. I'm involved with some large Drupal deployments so tools like this are getting pretty high on my radar.
