Consider multiuser systems where some users use KDE and some use gnome.

Hardly. I don't think that 2 services can nor should listen on the same
dbus adress.

Well, gnome-power-manager installs a 'trigger' that invokes a gnome
specific process. vlc could of course try to detect if it is running in
an kde or gnome environment and then decide to send or not send the dbus
signal.

But TBH, I feel that this check should better happen in some sort of
dispatcher that listens on org.freedesktop.PowerManagement, and then
invokes the "right" powermanager for the running desktop
environment. This would make it a freedesktop.org issue. In that case,
nothing would need to be done in vlc; it could continue to emit that
dbus signal and let the system decide what to do with it.
