Not so. Requesting it from a local node (i.e. < 10 ms ping) with a low HTL
results in no impact on the network except resulting in higher response
times for data that's already been transfered. Statistically, you are
correct -- the nodes on the same subnet are less likely to have the data.
Unless, of course, its already in their datastore, saving an otherwise
costly trip to the outside.

In any case, I'm not going to push implementing this for a while, but I will
defend my position.
