[I made this same comment to the IETF plenary last night, but I waited until the end of the program to get in line so that more significant topics could go first. However, the result of that strategy was that many people whom I think might have been interested to hear my comment had already left the room. So, I will bother the whole list now and apologize if you are not interested.] There has been a somewhat contentious discussion on this list recently regarding what has not been achieved in security during the last 10 years. This meeting of the IETF was also the 10th anniversary of the first audio multicast from the San Diego IETF meeting. Steve Deering and I were the primary organizers of that "audiocast", with plenty of help from many others to set up DVMRP tunnels ranging from Australia to Sweden. There has been an audio + video multicast from every IETF meeting since then. For one of those meetings (I don't recall which), the cumulative number of distinct hosts tuning in to the multicast during the week was just slightly higher than the number of physical attendees. I thank those who have taken responsibility for the multicasts subseqent to the first several that I worked on, including the U of Oregon crew who have handled recent meetings. I am disappointed that, like security, IP multicast has not become universally deployed in those 10 years. Perhaps both problems are just hard. I think we are making headway now on security; I hope people have not given up on multicast. Not coincidentally, this meeting was the 10th anniversary of the Audio/Video Transport working group that I co-chair with Colin Perkins. I suppose there may be some others that have lasted longer, but it still seems like a long time. -- Steve
