Any comments would be appreciated. The only thing that spice needs to do is export the fact that it's running on a slow link. gnome-settings-daemon will take care of reading that and acting accordingly. There's no need for spice to know what the desktop environment will make of it. > I have few additional questions: > 1.

The specification website is currently broken, but that's what I had: http://people.freedesktop.org/~hadess/idle-inhibition-spec/index.html It's only for enabling idle inhibition, nothing else. > 2.

It's a system plumbing issue, and inhibitors are for applications, so I'd be against it.
