[UPDATE April 15: Site Administrator for SharePoint 4.0 is now generally available to customers. Download the free trial.
I just made a quick video overview of the updated Information Portal that will ship with the upcoming Site Administrator for SharePoint 4.0 release. New features include streamlined product installation, support for SharePoint 2010, built-in security trimmed access to Information Portal for the site collection administrators, and the brand new permissions reporting.
Enjoy the video, share your feedback and stay tuned for release announcement later in April!
