P2P networks are teemed with dynamic nodes. When a peer leaves the overlay, it will transfer the stored resource records to a node which has a close node ID. From the perspective of an ISP's network, making P2PSIP node IDs with proximity property will reduce the network hops when data transfer happens. Besides that, I think overlay maintenance messages will also take less network hops if most neighbors have close node IDs. If node ID has proximity property, it will help for the peer selection when there are a list of peers providing the same resource. I think we can find some papers describing the proximity for DHTs. I agree with Bruce that there are many considerations when assigning node id.
