Right, but multicast appears to be a large part of the problem. I know this is heresy, but good engineers are usually able to use available tools. It is possible to use the handle of a screwdriver to hit the head of nail and drive it into the wall --- when you don't have a hammer. Now, it was a *naive* question, and others have pointed out the cost of unicast alternatives, so I am not saying "adopt commercial solutions today", but if we are only doing multicast for religious reasons AND it isn't reaching the large group of people who cannot participate THEN it might be time to consider some alternatives, that's all.
