FYI. I did a presentation to DLNA (which has a lot of key UPnP people) that warned them to start thinking about service discovery in the multi-router world, and the world where more and more Wi-Fi APs are limiting the multicast that makes it to Wi-Fi devices. I mentioned the DNS-SD proxy work, homenet, and told them: " - People have started to study the current quantity of multicast traffic and its impact on power consumption by battery-operated Wi-Fi devices. http://tools.ietf.org/html/draft-desmouceaux-ipv6-mcast-wifi-power-usage-00 http://tools.ietf.org/html/draft-vyncke-6man-mcast-not-efficient-00 - Concern is growing and proposals are starting to appear for ways to decrease the quantity of multicast messages. http://tools.ietf.org/html/draft-yourtchenko-colitti-nd-reduce-multicast-00 " My recommendations were that they had 2 basic options of either also supporting DNS-SD / mDNS for service discovery, or defining a SSDP proxy similar to what I expect will be done for DNS-SD. Anyway, I told them I'd keep them updated on the state of affairs regarding this issue.
