Hi, Charles This is again going back to what I brought up awhile ago that the definition of accessibility probably needs to take in consideration the audience/context/environment. The issue of accessibility of public pages can be different from pages used in specialized situations. An issue for universities is what is reasonable to expect a disabled student to learn in access technology before starting courses. Also, it might be easier to get DR to pay for equipment if universities can say up front what kinds of tasks students will be expected to perform, e.g. using IE 4/5 . An area I'm slowly seeing more happening is the web page not just providing content, but also being used as a more flexible/sophisticated interface. My suspicion is that students in long distance learning situations will be wanting more interaction and less just reading pages of text.
