My colleague and team mate, David Weller, has just posted a new video to MSDN.  It's a pretty slick lap around an application built by Accela with help from Keyhole and IdentityMine.  Using an emergency services worker scenario, the video clearly demonstrates the busisness value of some of the new technology coming in Visual Studio 2005 and SQL Server 2005 and then to top it all off it shows how Longhorn makes these types of scenarios even more compelling.

Very, very cool.
