I finally got an article on SCTs in a web farm live on MSDN.  The sample code needs to be installed the the same directory as the WSE samples (default C:\Program Files\Microsoft WSE\v2.0\Samples\CS\QuickStart).  There is an update that should be posted soon that removes this dependency.  You can find the article here:
