SQL Server 2008 Policy Based Management Screencast
At Magenic, Dan English and I are working on creating SQL Server 2008 screencasts highlighting the new features. He's already published a couple on his blog regarding Intellisense and Data Profiler task in SSIS. His explanation of what we're doing is so perfect, I'm just going to borrow it. 
"A new thing we are trying internally at work is sending out weekly 'Did you know?' (DYN) emails about new features that are included in SQL Server 2008. We are trying to spread awareness and excitement about the new version of SQL Server 2008. The emails include information about a new feature, links to the topic in BOL, a internal discuss in regards to the topic, and SQL Server 2008 information (main page site, trial download site, learning portal, webcasts, and virtual labs). The other item that we are including is a screencast of the new feature. "
Here is the screencast on Policy Based Management:
SQL Server 2008 includes Policy-based Framework
Policy-based Framework is a system for managing one or more instances of SQL Server 2008. Policies can be created that manage entities on the server, such as the instance of SQL Server, databases, and other SQL Server objects. Policies can be automated to ‘enforce’, ‘check on changes’ or ‘check on schedule’.
Policy-based Framework delivers the benefits such as: Compliance with policies for system configuration; Monitors and prevents changes to the system per policies; Reduces TCO by simplifying administration tasks; Detects compliance issues in SQL Server Management Studio
Read more about this in the SQL Server 2008 BOL ‘Administering Servers by Using Policy-Based Management’.
You can view the screencast about the new Policy-Based Framework in SQL Server 2008 via MSN Soapbox below, or youtube or download here.
