I wanted to point you to a great blog post that Steven Murawski wrote on how to use PowerShell along with the Microsoft Sync Framework. In the post he shows how he used PowerShell to create an "exploratory environment" for testing Sync Framework and he did this by converting one of the existing samples to PowerShell.
Thanks Steven, Great Work!
