Here is my understanding of this thread that I have been quietly watchig
from the sidelines.
WHat is being asked for is something closer to the windows model. In
other words if accessibility is needed by an AT app like orca then it is
started and runs. However if it is not needed it is not being used.
THis can be important on a computer used by many people where one wants
accessibility and one does not. In windows you simply shut down the
screen reader and the lag it introduces goes away which is not the case
in Gnome as far as I can tell.
Ideally of course there would be no difference between having an AT
program running and not but given that there is extra proccessing
involved that isn't likely to happen.
DOn't know if that is a correct reading but it is my understanding.
