Can't remember whether this has been raised before, but a random walk terminates at a given node with probability proportional to the node's degree; does this mean high-degree nodes are more likely to receive swap requests than low-degree nodes? Seems like that could be disruptive in two ways:
1) When a high-degree node changes its location, many other nodes are affected. 2) There might be some correlation between degree and other properties: high-degree darknet nodes might belong to committed users with large stores, in which case it's particularly disruptive if those nodes keep moving. Just a thought. Cheers, Michael
