Hudson CI can be hosted anywhere. ### Hosting on Engine Yard AppCloud +Using Engine Yard AppCloud "Quick Start" wizard, create an application with Git Repo `git://github.com/drnic/ci_demo_app.git` (any arbitrary rails/rack application), and add your own SSH keys.

There are no guarantees what will happen. I expect bad things. * You must name your CI environment with a suffix of `_ci` or `_hudson_slave`. \ No newline at end of file
