I'll have to admit that this is a bit of an ambitious webcast.  In 1.5 hours, I plan on covering LINQ to Objects, LINQ to XML (including VB9 Xml Literals), LINQ to SQL (Inserts, Updates, Deletes, Stored Procedures, and Concurrency), Using LINQ with ASP.NET, and using all three (objects, xml, and sql) in a single query which joins the respective data into a single result.  This is my first run of this content, so I would love to get some feedback.  I've rehearsed it and think I'm within the time slot:).  The webcast is at 2pm EST.  Details are here.
