Section 508 requires that Federal agencies’ electronic and information technology is accessible to people with disabilities. Section 508 was enacted (as an amendment to the Rehabilitation Act) to eliminate barriers in information technology, to make available new opportunities for people with disabilities, and to encourage development of technologies that will help achieve these goals. Section 508 law is most relevant to Federal Government agencies, but is increasingly being discussed at the State and local Government levels too.
The official Section 5508 site is at http://www.section508.gov/, a site built entirely in ColdFusion MX.
In addition, Gareth Slinn just brought an accessibility tool that he built to my attention. Go to http://www.hermish.com/ to access an online accessibility test tool. It parses specified URLs and checks for Section 508, WCAG, deprecated elements and attributes, and more. And this too is powered by ColdFusion.
