This does seem like an interesting idea. To expand upon it, I think
GNOME also needs a solution that works more generally.
There has been talk of enhancing gnome-settings-daemon so that it is
possible for users to hit particular keybindings or other sorts of
gestures (e.g. mouse gestures) to launch AT programs. This would
allow a user to launch the on-screen-keyboard, text-to-speech, or
magnifier by completing the appropriate gesture (e.g. keypress or
mouse gesture).
I would think that using a specific smart card or USB stick is another
form of "gesture" that would also be good for launching AT programs.
However, wouldn't it be better to come up with a solution that would
support all of these sorts of "gestures" in one place?
Providing a solution that can recognize different sorts of gestures
(perhaps configurable so users can define their own sorts of gestures -
perhaps with other unique hardware based solutions - like pressing a
button on their braille display) seems a way to go about implementing
your idea and also supporting other mechanisms that could be used to
launch AT programs as needed.
