The patch below attaches X11 properties to a Screen, not a Display. Using
it, I am able to do the following:
leszek# pax11publish -D ":0.0" -O alsa_output.pci-0000_01_06.0.analog-stereo
-e
leszek# pax11publish -D ":0.1" -O alsa_output.pci-0000_00_07.0.analog-stereo
-e
leszek# xprop -root -display ":0.0" | grep PULSE
PULSE_COOKIE(STRING) =

Now I try playing something from :0.0 - sound correctly gets routed to
alsa_output.pci-0000_01_06.0.analog-stereo
However when I try to play something from :0.1, all I can hear is silence. I
notice that for some reason PULSE_SESSION is missing from :0.1's root
window. I add it:
leszek# xprop -root -display ":0.1" -f PULSE_SESSION_ID 8s -set
PULSE_SESSION_ID
571eae318b6377f95367e6524abdec09-1256566213.375419-376893987
..and everything works!
Apart the problem with PULSE_SESSION, there is another one: the above
confuses gnome-volume-manager which seems to completely disregard the X11
props.
