This is actually controversial, even within GNOME. There is at present 
no acceptable alternative.

The existing D-Bus approaches have some serious problems which have not, 
to date, been resolved satisfactorily. The KDE folks working on this do 
need to work closely (more closely, IMO) with the Gnome developer 
community if they hope to migrate the solution to D-Bus.
