I used to work with Michael at a previous company, one of the most creative coders around any certainly worth keeping an eye on...He also has a really interesting post on Web Accessibility which links to a report pointing out some of the problems with current accessiblity testing tools...which is a bit of a pain, especially if you need sites to be truly accessible (of course ASP.NET 1.1 is not compliant at the moment - ASP.NET 2.0 fixes many of these issues though).
