>I don't know why remoting would be any better than Web Services in this example. We have not used Remoting or COM+ in any part of our application at
I didn't read the example, but baisically, with remoting you can send more information in a smaller package (binary) since you can control both sides of the connection.
If you only control one side, and want to exposed something in your app to others who consume that service the standards of Web Services is the way to go.
