Wrox has a book on SQL Server 2008 and PowerShell HERE. The book is due June 2009.
I just noticed that they have recently made the scripts from the book available for download.
The zip file contains: 76 .ps1 scripts, 26 .sql scripts, 2 .xml files, 1 .bat file, and 3 .txt files. I’ve not looked through the scripts, but to include over 100 PowerShell and SQL scripts is super cool.
I can’t wait to get my hands on the book and review it…
[Edit: I originally reported 107 .ps1 scripts, but I was wrong.]
