1.  Does universal design mean that the experience of one person has to be
    limited so that another person can have a similar experience,
    e.g. a slick, flashy design?

2.  If there is a technique which some people can use to speed up their
    use of information, but other people can't use and will be slower
    at processing information, should the technique not be used?
    What if there is no other equivalent technique that increases
    the speed that a person can use the information?

3.  Does a person using access technology have the same experience as
    someone not using access technology even if they are referencing
    the same web page?

You have raised some really important points here. I am grappling with those 
issues daily in my role within a University as academics and developers resist 
strongly the notion of reducing the functionality and/or state of the art 
features of their Web pages to accommodate a base "universally accessible" web 
site.

A recent example might illustrate the point that universally designed sites 
can provide better functionality for all users - not just people with 
disabilities.

I describe that briefly here:

One of our requests from faculty was to develop an interactive simulation of a 
satellite communication system. I have spent a great deal of time working with 
our designers to ensure they are aware of the W3C and Section 508 guidelines 
and make every effort to follow these guidelines in their development work. 
The programmer met with an academic from the School concerned with the 
development of this satellite communications program. While the academic was 
open to suggestions, neither the programmer nor the academic would accept that 
there was any way of reproducing this interactive experience for visually 
impaired users since the output is essentially a simulated screen display of 
what look like satellite dot patterns. At the very least we agreed we could 
use alt tags and longdesc to describe the simulation's functionality but that 
of course represents a different experience than the original concept.

I emailed Norman Coombs asking him if he had come across anything that could 
meet the requirement of the simulation in a way that could be accessible for 
people with disabilities. He sent me a prototype of an auditory graphing 
program which has a similar display (scattergram plots). Although a different 
application entirely, the academic and programmer could immediately see the 
potential. Essentially the auditory version narrates the options (ie x and y 
coordinates) that can be changed by the user and the changed visual display is 
accompanied by auditory signals (a bit like Morse code) which change pattern 
according to the pattern of dots on the visual display. This is true universal 
design - the auditory signals in fact make the simulation a more enriching 
experience for all students. The ability to selective turn off visuals and/or 
sound provides maximum flexibility and caters for different learning styles as 
well.

In summary, to me, universal design is challenging our traditional "narrow" 
view of what can be achieved. It forces us to move outside our current 
experiences to be innovative in order to create powerful, flexible web 
environments that cater for a variety of user needs.

Just my experience but thought it worth sharing....
