Just noticed this link in a post on Kent Sharkeys blog. The article by Scott Mitchell covers various methods of making ASP.NET 1.1 based sites conform to WAI accessibility guidelines (or US Section 508 if you prefer :-)).
It is still stunningly annoying (and frankly unbelievable) that the ASP.NET Hotfix Rollup is still not easily downloadable - almost a year since it was released, neither have I seen it on the MSDN subscribers download site (although apparently a few CMS 2002 updates actually include it!).
