Dear dnssd wg, The requirements draft still has failed to consider new security considerations caused by exposing link-local information to adjacent networks. This goes well beyond being mere unions of mDNS and DNSSD issues. One solution might involve use of overlay network addressing, for example. Without a well considered strategy, no firewall will be able protect local networks. Regards, Douglas Otis
