Important point - not everything in WPF is in Silverlight 2 (obviously) but what is there is API compatible so, for example, you can take Silverlight XAML and re-use that in WPF.
LOB Applications - Cirque du Soleil casting application. A handful of people worldwide can perform some of the roles CDL are looking for so talent scouts work remotely and need to upload their data to central casting database. Using a local cache the artist is evaluated and compared with existing talent pool. Sync'd when scout has connectivity. On the flip side, when trying to cast a part, can review the possible candidates including, eg, video of their casting session.
