SOK doesn't support any kind of switch-only user, nor does it support
scanning users.  It can only support users who can both point with high
accuracy, and click.

You will find that the pointer-grab problem will defeat many of your
cases if you try to access menus and control programs via AT-SPI.

Toolkit maintainers and authors argue very convincingly that the
problematic behaviors regarding pointer grabs are NOT bugs.

After years of dealing intimately with these problems I am 100%
convinced that any OSK technology that doesn't use some alternative
means of avoiding these pointer grabs is doomed to fail for these users.

For a pointing-only user (who cannot perform a mouse click), these are
lockout scenarios which effectively hang their desktop sessions, so
these problems are very serious indeed.

There are some in the default gdm.conf file, but I am not sure they
would be the best choices for cross-desktop defaults.  If there's a will
to standardize this I suggest we discuss it on
accessibility lists freedesktop org 

I like this idea.  Making AT-SPI load dynamically is theoretically
possible but there are some real feasibility issues; realistically I
don't think it's going to happen anytime soon (though there has been an
RFE open for years).  But allowing a user to request assistive
technologies (or detecting that need via 'gestures') at login time is
very feasible.

It would probably be the fastest path to getting it integrated with
Orca, etc.
