It would appear that a purist IP architecture for all switching nodes in the Internet is both feasible, and for management reasons (and therefore cost), attractive. Because (and not despite) of the work done on QoS and scalable ATM switch design, it would seem that the exposure of ATM at any interface is completely unnecessary, except perhaps, at modest speed links (ADSL, DVB, or 25Mbps Domestic networks?), where the reduced latency for voice/video on multiplexed at finer grain may need the cut through cell size.
