The Buildbot also offers a PB-based status client interface which can display real-time build status in a GUI panel on the developer's desktop. This interface is normally anonymous, but it could be configured to let the buildmaster know which developer is using the status client. The status client could then be used as a message-delivery service, providing an alternative way to deliver low-latency high-interruption messages to the developer (like “hey, you broke the build”).
