Craig McMurtry released the code for his Live Service Trace Viewer on his blog today.   Live Service Trace Viewer is a tool that alows you to view trace information between WCF nodes.  The trace information is provided in a visual/WPF view.   You can read more about this tool and download the code from here.   There's also a new video on Channel9 where Craig gives a demo of the tool

BTW, if you want to work on cool stuff like this... I'm hiring.
