The container widget is a Plasma::Applet, and Applets in Applets = bad and 
troubles, so it is a nice toy but it is a temporary solution prone to 
problems.
Containment in applet instead, is simply impossible. Plasma::Containment needs 
a Corona to work, and to provide a Corona you must embed a QGraphicsView in 
your applet. But Qt will protest because a QGraphicsView can't visualize 
itself, cause it is in the same scene it should show. Showing in a 
Plasma::Dialog doesn't change the thing

Believe me, i've tried and tried for months to do what you want, and realized 
that GroupingDesktop is the only right way.
