60Ghz is very directional.
Combined with phased arrays you could get ~10Gbit to any machine you can see directly (opposite side, perhaps 1 or 2 rows up and down) without restriction to the number of pairs.
It actually sounds extremely useful for something like Hadoop because it doesn't require extremely fast switches since communication can be made through a less centralized means.
