What would be really interesting is a service that would tell me the build status and code coverage metrics for each version of a dependency I use in my project (and each dependency they use their projects and so on).

Even more interesting would be something that would attempt to force code coverage analysis on projects that use a standard testing framework, have a certain amount of tests present, but don't have CC configured in their project.

At first I was thinking that is what this service did but it doesn't appear to be the case.
