It is important for accessibility to have a solution for this - and also for 
the case where an application is running on a remote machine.

We plan to support GNOME's accessibility framework (AT-SPI) in KDE4 to give 
screen readers access to KDE applications. AT-SPI currently uses CORBA, and 
we are tying to convince the GNOME team to migrate it to D-Bus. Missing 
network and sudo support in D-Bus is one of the main obstacles.

If someone already knows a solution for this, then please add it to
http://www.freestandards.org/en/AT-SPI_on_D-Bus - otherwise we will need to 
try to find a solution on this list.
