Hi,

I think that the issue of a single web page might be changing in version
2.0 of the guidelines.  Recently, someone sent me this info about 2.0:

     http://www.w3.org/WAI/GL/wcag20-requirements
     
     RE: CLIENT SIDE AND SERVER SIDE SOLUTIONS
     S1 - serving content in different forms is an acceptable way to comply
     with the guidelines as long as equivalents for all of the information
     are provided in the different forms and it is all available through the
     same URI (though it may be linked to it) (server side solutions are
     acceptable - as specified)
