Reading this, I noticed that DigitalOceans' Docker pre-built image is not mentioned anywhere in the dockumentation. Would it be worthwhile to include that somewhere? I don't have any experience with AWS and Rackspace to compare, but am currently fiddling with Docker on DigitalOcean and found it to be a quick way to get a Docker host running in no time.
