So even when the window is hidden or not focused or whatnot? That's 
more of a desktop integration issue, isn't it? Maybe there is a FDO/XDG 
method for registering them.

In any case, I imagine you'll probably want to implement 
GApplication/GtkApplication and have you app raise/focus/etc the window 
in response to the activate signal. The desktop then just needs to 
activate the app in response to the global shortcut, by invoking that 
signal via DBus or by executing a new instance of the app, which would 
also send the signal to the already running instance.
