Wayne Sheffield has a Powershell cmdlet to find sessions matching SQL Saturday topics:
The output to the screen is the Event #, Speaker, Session Title and URL for the presentation.
The generated export file will also include the event name and session abstract. Additionally, the URL will be encased with the Excel HYPERLINK() function. When the export file is opened up with Excel, clicking the URL will open your browser to the session information, where the presentation material can be downloaded.
I hope that you get a lot of use out of this script.
