Petar Maymounkov, in his description of Kademlia, shows that in the Gnutella network, the longer a node has been alive, the more likely it is to stay alive. Does this suggest that the liveness "pings" should follow an exponential backoff as well? (in addition to the NAT traversal pings, I mean) Or is this behaviour likely specific to Gnutella and is unlikely to be found in other P2P systems?
