The slides from ODC 2008 are made available on the OBA Central website.

The slides are categorized into a few categories:

• Architecture (those planning a full scale deployment of OBA should read this!)
• Client (incl. coverage of some lesser know product for OBA i.e. Access & Groove)
• Executive
• Server (ala SharePoint, look out for stuffs on BI and Authentication)
• Services (SOA & S+S)

One of the cool thing I saw from the slides is a 3d Silverlight webpart for Plant Floor OBA RAP (pic below).
