The server is implemented as a WPF application though. Has anyone tried to create a silverlight application instead of the WPF sample. Any jump start on this is appreciated?

Code wise it will be the same. The only problem I see is that the Silverlight app and the services will need to be in same domain else cross domain file is needed for the Silverlight to connect to the service.
