I mentioned TFSBuildLab a month ago when it hit beta 1. Peter Blomqvist and Mathias Olausson have been hard at work and have now released beta 2. They expect to hit 1.0 in the near future. If you are looking for features like continuous integration and scheduled builds in TFS 2005, you'll want to give this a try.
What is new in Beta 2?
Support for tracing using trace listeners
Made automatic notification registration optional
Removed the need for LDAP to resolve email for notifications
Context menus with refresh commands
Full screen mode (press F11 to toggle)
Added hosting of reports in the dashboard
Minimize to tray
Sorting possibilities on the contents of the grids
Added Edit trigger/policy
Added Copy trigger/policy
Added support for executing alert commands
Notifications occurs when a build starts as well
A policy for restricting checkins based on a source control path
A policy for restricting checkins when the build is broken
A policy for requiring a comment when performing a checkin
Peter has posted about their own dogfood statistics.
We have now been dog fooding TfsBuildLab in production since 2007-04-24 on a several projects the largest of them consisting of 5 parallel development branches each containing approximately 10 000 source files.
Some statistics since the start (didn't have the time to do the graphs this time):
1854 Automatic cleanups
935 Scheduled builds
754 Continuous integration builds
