Yes, I think this is called "demands attention" in the API.

The attached patch (for kde-runtime.git) should give you a starting point.
It doesn't work (maybe because the window gets focus?),
and it should obviously be put under a different option name, I was reusing
--keepbelow just for quick testing before going to work :)

I'm CC'ing the kwin mailing-list where the kwin experts will be able to help 
with this much more than I can do myself ;)
