I guess Moore's Law comes into play again. One will need some
pretty hefty TCP buffers for a single stream to hit those rates,
unless latency _really_ drops. (Distributed CDNs, anyone? Speed
of light ain't getting faster any time soon...)
Of course, IMHO I expect DCDNs to become increasingly common...
but that topic would warrant a thread fork.
Looks like RR ISLs are feasible between GigE+ core switches...
