 KDE3.1.2 KWin actually can do Alt+Tab active window changing while doing DND 
with Qt apps (and Ctrl+Fn for desktop change etc. too). Qt apps have only 
mouse grab while doing DND, so it's possible for KWin to get the keyboard 
shortcuts. Qt still gets all mouse events, and also gets keyboard modifiers 
status, as they come in the mouse event too. The only drawback I noticed is 
that when the mouse is idle and one presses/releases keyboard modifier, Qt 
won't notice. But I guess a little XQueryPointer() polling when no input 
events are available will solve that.

 I personally find this better than this suggested MAY_RAISE protocol, which 
looks more like 'focus follows mind' technology to me (famous term among KDE 
developers ;) ). Hmm. Perhaps seeing at least a proof of concept test app 
would help.
