Is this switching supposed to happen globally for the whole desktop or for the 
application that currently has the focus only? Both lead to different 
approaches as how one could implement the IM switching.

A global switching could be implemented using an XChangeProperty on the root 
window (that's what KDE currently uses for things as the style change 
notification). If the switching is only supposed to affect the current focus 
application we need some more sophisiticated solution.

I would also prefer if we can try to get the same switching mechanism 
implemented in both Gnome and KDE/Qt, so that all applications will work with 
the same and you only need one switching application.
