The above also suggests that the configuration variable that lets you specify the protocol version should hint in its name which direction of the protocol it controls. Even if we decide that we'd add only the variable for the initiator side for now, if it is possible that we later may want to add another for the acceptor side, we need to do it right from day one. Perhaps protocol.connectVersion(s) vs protocol.acceptVersion(s) or something like that?
