I certainly don't consider it an irrelevancy. The math and simulations on which the darknet location swapping is based assumes a well connected network - I think it is entirely legitimate to ask whether poorly connected networks will work well. For example, what does happen if you have a sub network which has very few links to nodes outside the sub network? We should investigate this, but it should be done in parallel to release of 0.7, ideally by people other than Matthew. It should not be a precondition to the release of 0.7, nor should it delay it. > One proposal we had for performance was tiered routing: route to fast nodes > first, then medium nodes, then slow nodes.

This is worth trying, but it absolutely would have to be simulated before deploying it on the live network.
