In our office, an old, noisy and power-hungry Windows PC was running just to display a build monitor. Eventually I wrote this build monitor to replace the old PC with a Raspberry Pi (thanks to Lars for the motivation).
I've been running Radiator successfully for over a year now with a number of Jenkins installations. That said, Radiator has only been tested with Jenkins installations I use.
But one of the great things about open source projects is that anyone can contribute, isn't it? So please write bug reports, send pull requests and contribute!
