Ooh, the farthest pair problem (in an N-dimensional vector space, though).
I'm pretty sure problems like this has been studied quite extensively in the
literature, although perhaps not with the same norm. It's known under both
"farthest pair" and "diameter", and probably others. I'm fairly sure it
should be solvable in at least O(n log n).
