There seems to be a little misunderstanding here; from what I gathered when talking to Larry, the idea behind ccClusters is that they provide a single system image in a NUMA box, but with separated operating system kernels.
Of course, this is close to what a "single" NUMA kernel often ends up doing with much ugliness, so I think Larry's idea to construct NUMA OSes by putting individual kernels of nodes to work together makes a lot of sense.
