I like the status email sent by TFS\'s alerts mechanism when a build breaks. However I would like to send such an email to the entire team and not rely on the team to subscribe
Brian the Build bunny is nice but the Nabaztagtag WiFi Rabbit bunny is pretty expensive and is currently out of stock.
The Team Build Tray Notification that comes with TFS is ok, but:
So there's an open source project on Google Code that runs in the tray that's available on Google Code: http://code.google.com/p/siren-of-shame/. That project can work independently but it's designed to work with a USB Siren that is available for sale.
