The main reason renting e.g. dark fiber wouldn't work is not
just relativistic latency (it can be partly ameliorated by 
custom, mostly ACK-less protocols), it's the cost of connectivity
which is exponentiated by distance. 10 GBit/s cables are already
expensive enough for ~m distances.

In short, you need local clusters. Due to volume/surface ratio
scaling WAN would work for very fat nodes. Maybe, for a PS7,
on GBit/s residential broadband?
