My use case is volume control UIs (pavucontrol, gnome volume control, etc) - they can use the information to hide three of the four HDMI ports, keeping only the right one. Or hide headphones when they are not plugged in. But in Ubuntu 11.10 no client actually uses this information, which is why the protocol skew was a mistake. -- David Henningsson, Canonical Ltd. http://launchpad.net/~diwic
