I could see how a low-latency interconnect would help with a
Second Life-like virtual reality, where most things happen
server-side. On the other hand, given that low-end servers
come with 4 GBit Ethernet NICs, just distributing the game
world across a 2d torus would do as well, or better.

Has anyone ever heard of a cluster wired in a diamond
lattice (made from tetrahedrons) topology?
