Three years ago I proposed using Ulam Spirals as the peering logic for Bitmessage (decentralized, trustless messenger service). Essentially with Bitmessage you trade messages with everyone on your network but you can be a member of multiple networks. My proposal was to be in one network but peer with with all the "touching" digit peers according to the Ulam Spiral. The benefit of this approach is that newer (higher value) networks are peering with older more established ones and there are multiple paths between non-touching networks to send messages.
