My opinion...

	The need for QoS is driven by application users.
	Although IntServ model is more of an academic challenge (exceuse me
	Lixia).. DiffServ has real business implications.

	Almost all the equipment vendors has a story on the 
	QoS (DiffServ) and QoS-MPLS interaction. If ISPs ignore application
needs
	and cannot encash  on the equipment features ... too bad they
	are at loss.

QoS is an apparent need in the access but it has major implications
and revenue potential in the core (at ISP borders) also.
