Hudson Notifier?
You can try Catlight. With this app, you can choose jobs to monitor. It runs on Windows and OS X, and can also connect to Jenkins servers that require user authentication.
I recently started development of Jenkins Tray, which was forked from Hudson Tray Tracker's code base.
If you switched over from Hudson or Cruise Control.Net to Jenkins, this tool maybe useful to you. It resembles Cruise Control.Net Tray, to some extend.

Hope that helps.
I think this is the best notifier so far. Hudson Tray Tracker: http://code.google.com/p/hudson-tray-tracker/
