Progress Notification for Web Service Calls

In one of our current projects, we had a need to provide progress indication for web service calls that could take a long time to execute (by design - alot of data being transferred).   It turns out that this is a perfect scenario for using SOAP extensions, in order to get into the processing pipeline and provide the necessary information.  Kim Major, our senior developer, wrote a great article that clearly explains and shows how to do this.
