  == BoF agenda and discussion ==
  
+  * Problem with screen reader etc. not working on apps running as root is that accessibility libraries are finding the accessibility bridge by looking in /tmp/orbit-$username-of-current-uid rather than something to do with the display.  See http://bugzilla.gnome.org/show_bug.cgi?id=163132.
+  * As a side-effect, this means that a11y doesn't work with remote X displays (eg, LTSP)
+  * The real fix for this is too complicated for us.
+  * However, we think we can make it work by patching the at-spi bridge lookup to use SUDO_USER.  This is a grievous hack but doesn't make anything any worse.
+ 
+  * Another problem is that the display-grabbing of gksu prevents the use of a11y tools with the gksu interface (eg, on-screen keyboard).
+  * There is a gconf key named ??? which can disable this display-grabbing.  This "solves" the problem in that it makes it possible to use gksu with a11y tools.
+  * It is not currently clear what the real best solution is; there are good reasons for the grab and naively it would be nice if we could somehow exempt the a11y tools but this is hard (the grab is at a very low level)

  SvenJaborek: just an idea, try executing xhost + as user before starting the admin tool
