If KDE really is as fast and memory efficient as claimed, this should not be 
an issue.  At least the code will be shared memory wise.

Again, do you really want a computation or modal dialog opened for an

Have you ever seen the recent file list in KOffice staying in sync between

depending on how I invoke KWord (running another instance or clicking File / 
New), I get different behaviour.  That is not desirable.
