AFAIK, there is no implemented multicasting protocol - routing and reliable transport - that can scale to the number of groups, senders and receivers visible in current IRC networks. Source-based trees would require the order of 1E6 (S,G) pairs and core/RP-based routing would be an even easier target for the SK's than IRC already is. Achieving instant group messaging on a global scale with convential multicast is unlikely. Relevant academic research continues. J
