For the case you, dear reader, are not subscribed to the KDE-accessibility mailinglist (tststs), we received a rather interesting mail just yesterday; Project Announce: AT-SPI D-Bus
That project is done by codethink and sponsored by Nokia and Mozilla (and Novell seems to be in there somehow too). Result will be (hopefully) also that each Qt- and KDE-application will be able to access optional the same accessibility-infrastructure like e.g. GNOME is using today. For this Qt4 provides the Qt Accessibility framework and the best; no additional work at the application-level is needed (well, with some exceptions as usual).
Yay, another good day :-)
p.s. what's going on with freedesktop.org? Why does it take 6 month to provide an svn-account for that project and akonadi still waits for one since more then a year now iirc. Not enough admins or are the accounts managed using Active Directory?
