I've been playing with SQL Server 2008's new spatial data types recently, and toying with the idea of using MapPoint (Bing Maps?) to visualize my SQL Server-based spatial data. In a happy twist of fate I accidentally ran across this MSDN webcast event for a MapPoint Add-In for SQL Server. The event is scheduled for July 29 @ 10 AM Pacific time and requires registration at http://msevents.microsoft.com/CUI/WebCastEventDetails.aspx?EventID=1032420635&EventCategory=4&culture=en-US&CountryCode=US.
