One of my friends just showed me a
CruiseControl plug-in for FireFox. He uses it with the CCNet Java version but was convinced that it will work with .NET as well. I was skeptic but we gave it a try. To my surprise it works! You only need to give it an URL to your build server dashboard. It shows the status of each project in browser status bar. I presume it uses some HTML parsing and the pages are similar both on .NET and Java versions. Not all things work though. Also it's not that much useful as the CCTray but it's a nice gadget.
