Same story goes for "clusters" of backbone routers. When ANY router becomes as reliable as a dumb TDM device, then maybe we can begin collapsing the POP topology. However, the very nature of the Internet almost prevents this reliability from being achieved (having a shared control and data plane seems to be the primary culprit). There are routers out there today that can single-handedly replace entire POPs at a fraction of the rack, power, and operational cost. Hasn't happened, tho. I don't like wasting ports for redundant n^2 or log(n^2) interconnect either, but router and reliability mix like oil and water...
