It might be of interest to do testing of blind computer users
with varying levels of screen reader ability to see who may or
may not be stonewalled by what kinds of visual effects.  For example,
what co-relations are there between form layouts which use different types of
visual effects, screen reader skills and success in filling out forms.

Just to be sure I understand, in your statement:

    "That presentation should be delivered from the same data set and in
    the same way to me as it is to one who has a different need than I
    for a presentation."

does this mean that you want the same presentation as everyone?  Is
this consistant with the consensus statement from wcag 2.0?

     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)

I be misinterpreting the text, but it looks like there is not a requirement
for all users to be able to use the same form/version.
