Making TurnKey easy to deploy on as many public and private clouds is an important goal for us. We're going to soon be expanding the number of image formats TurnKey officially support to include more major contenders in this space. We'd also like to establish a mirror network that supports rsync so that service providers will find it easy to get up-to-date images of all TurnKey appliances. By the way, if an rsync mirror is something you would find valuable, drop me a line.
