Pretty nifty.
One thing, while I have the ears of you Rackspace people: offer more documentation maybe? Kind of like how Linode does: https://library.linode.com/ Common things like how to run a mail server, how to get a LAMP/LEMP/LNPP/$XYZ setup going on, etc. Not full books or anything, just stuff to get things off the ground more easily when playing around. This is one of the reasons why I was so attracted to Linode, the docs, and the support whenever I'd join their IRC channel. It was good stuff, to get things running even though this is not my field by trade.
