Here are the slides I was showing on the Longhorn Airlift AD PowerShell session:
Overall the session went well. I was surprised that a big part of the audience was not that familiar with PowerShell as such but everyone seemed pretty interested and I saw people taking notes during the session.
We used Longhorn Beta 3 for the demos and everything went surprisingly well. I even demoed experimental cmdlets for granular password policies.
P.S. In case you get the DVD and listen to the session or just were there. During the demo I completely forgot to mention that the new-account.ps1 script I was showing while demonstrating the ADSI approach is from Adam Bell. Thanks to Adam for providing that on his blog!
