I can't see how this is better than doing multicast over ipv4 using UDP or something like that, code which we have already and has been tested for decades. I really don't want to apply this stuff, it looks bloated, complicated, and there is another avenue for doing what you want to do. Applications have to change to support the new multicast facilities, so they can equally be changed to use a real transport that already supports multicasting.
