Comment 45 for bug 328575

Another possible solution is an X11 transport for dbus, btw. Which allows 1 X server to 1 dbus always, even without ssh or su changes.

The only trick at that point is that stuff on the same X server and dbus-daemon doesn't have to share a home directory.

I guess this is an implementation of "Possible direction 2" from comment 23, but without having to modify ssh or su.

"Possible direction 2" is the least amount of work to get to a solution that is reasonably well-defined and functional, perhaps. But it means killing off autolaunch...
