If you could make a self-hosted Jenkins replacement that is even half as good as Jenkins (think extensions) but written in not Java, I think it'd receive a lot of positive reception.

The trick with CI, like task/project management software, is that people don't look at what works. They don't try and compete on intrinsics like stablility, extensibility, etc, and really after 12 months on any platform, any mid-large size company is going to care more about those things than new shiny.

Jenkins had the absolute worst UI for a long time, and it still was many people's top choice for CI. You're generally writing a tool for programmers, after all.
