I'm glad to see that David's blog got reactivated with the release of CAB. David Hill was a great supporter throughout CAB project - he did some key implementations at customer accounts that fed a lot of  'been there, done that' experience, I think he essentially picked the name, and was a general instigator across Microsoft of the importance of the scenario, and reviewer of our final application block. David is now working on the Windows Forms team on how these concepts can make it into the .NET platform & VS.NET...and he's actively in the CAB community, so seek him out and don't hesitate to tell him about your experiences in the space!
