Rather than matchmaking spatially, I reckon such a system would measure the round trip time between the players and the available server locations. That's something that typically happens manually when folk sort servers by latency. Very similar idea, but you could imagine two players being physically close to each other but electrically far away, due to things like being on different ISPs.
