Ok... by popular demand, I am posting all the demo code for the security webcasts on my website.  Link is here:  http://www.wjsteele.com/democode.zip.  (The file size is ~5mb.)

Also, don't forget, I have a webcast Today (at Noon EST) on Canonicalization and Unicode Issues/Weaknesses and I have one Tomorrow (at Noon EST)on ASP.NET Web Application/Web Services Security... sign up for them at http://www.microsoft.com/webcasts.

Have fun!
