I tested the very recent bits of at-spi2 in sugar-jhbuild and they
seemed to work fine in that accerciser was able to navigate through
the controls of the desktop window and of activities (applications).

Accerciser showed that it could not go into the HippoCanvas widget
that is used in some fundamental parts of the Sugar shell and also
inside our browser. The browser is moving from xulrunner to webkitgtk+
which I expect to fare much better there. About HippoCanvas, I have
been experimenting with replacing it with custom GtkContainers and
dropping Hippo completely seemed very doable.

I have no idea of what this entails, but as we have kept quite close
to GNOME's architecture, I expect the fairly trivial port to suffice.

Tried out Orca in Sugar and it was able to read windows titles,
buttons labels, etc. What GUI would it have other than a configuration
parameter for starting it automatically at startup?

The Uruguayan deployment has customized their builds in this direction
but I believe they need help upstreaming it.

Hippo is also the roadblock here.

No idea, I started this thread to find out :)

Thanks a lot for the great insights!
