* It would seem to me then that the UI should be tested, at the least,
for accessibility with Orca and the magnification application for
gnome (or any other windowing environment anticipated to be used),
with Firefox. I would recommend user testing with users who are
familiar with these ATs, but also with users who are not familiar with
these ATs, as there is a good chance that an individual using this
product may be unfamiliar with the linux environment. Since keyboard
commands are reasonably similar for most screen-readers (with some
exceptions) it would be reasonable to assume that a screen-reader user
would be able to acclimate themself to the new AT with little
difficulty. Perhaps this is already in the plans.
