A clever idea. People are wondering why such a thing might be useful, so let me advance a theory:

Latency.

Suppose you have a bunch of people somewhere, say, the US, and a bunch of other people somewhere else, say, China, and there's an ocean in between. If they need to work collaboratively on something, placing a datacenter in one country or the other yields asymmetric latency; someone has a lot more.

If you can just plop a datacenter exactly at the midpoint, everyone wins. It needn't be the biggest datacenter ever, just one that can handle the latency-sensitive tasks.

Neat project.
