Source code for SCT tokens in a Farm source code

I had a question on the source code for this sample.  The link is in the article tucked near the top.  Here it is too:

This particular sample needs to be installed to the same directory as the WSE samples.  There should be an updated version soon that removes this dependency, and a readme file describes the necessary setup steps that is installed with sample.  Note that you will also need to install the sample WSE certs for this to run.  Instructions can be found in the WSE documentation (default location is: Program Files\Microsoft WSE\v2.0\Samples\CS\QuickStart)
