Ron Jacobs just put up a new video demonstrating the Routing Service over on 10-4, the series of videos put together to show off what's new with VS2010 and .NET 4.  The 10-4 videos are located here, and Ron's quick demo of the Routing Service is Episode 40.  You can also find Ron on his blog, and more about WCF and WF over on the Endpoint Blog.

 Enjoy!
