Digitally Printed Packaging: Opportunity for Commercial Printers?

Can these value propositions apply to digital print for packaging? If so, why haven't we seen more digital print in packaging? And is there an opportunity for commercial printers in digital packaging?

Packaging includes metal and glass containers, corrugated, folding cartons and flexible packaging. Corrugated also includes litholam, where a paperboard top sheet is printed, generally offset (litho), and laminated (lam) to corrugated for point-of-sale displays and cartons. The litholam top sheet is typically a coated cover or folding carton grade of paperboard. Packages also have labels, of course, and labels have seen the greatest development in digital print for packaging.
