  == Design ==
  
+  * '''AT-SPI sudo communication:''' A connection can be established by patching AT-SPI to use SUDO_USER in it's lookup routine. ColinWatson will prepare a patch for testing.
+  * '''preventing focus-grab:''' This behaviour is determined by the gconf key {{{gksu:disable-grab}}}. It cannot simply be disabled, because it makes the desktop session a bit more secure to snooping for most users. It could be disabled by default on the Live CD access profiles, and/or a check box could be provided  on the Assistive Technology Preferences dialog.

   * 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)

  SebastianHeinlein: you can disable the grabbing of the keyboard by gksu. change /apps/gksu/disable-grab in gconf to true.
