We're thinking seriously about using Hudson (http://hudson-ci.org/) to automatically run our APEX unit tests on a nightly basis and distribute the results if tests failed or coverage drops below a certain percentage.

Is there any interest in participating in this project if we make it open source? Since Hudson is open, we'd be inclined to contribute back to the community.

Is anyone else doing something like this on some other CI tool like CruiseControl? We currently have a cron-based java solution for it running on a dev box, but we'd really like to take advantage of the trending and build-status tools that hudson provides.
