DNR-TV has a great talk\demo with Billy Hollis on a next generation business applications in WPF and Silverlight.  Billy is working with a customer to provide a temp worker to job matching services.  So far the application is in WPF, but they are planning to create a Silverlight version as well.    Watch the web cast for a full demo.

A few things I thought was cool:

1. They use visual clues effectively to direct the users attention (for example per-entity model pop-ups)
2. They multiple-module editing model.  Many records can be edited at the same time.  There is great navigation and notification support to manage all of this.
3. Dirty tracking seems nicely done.

Billy, we are all looking forward to playing with the real thing! 

Here are a few screen shots:
