Using DDS to deliver data to X machines over multicast, with some real time (soft) QOS is a powerful solution. For things like avionics, industrial automation, etc. I think if the server world ever thought about the advantages of multicast, it might solve some problems there. There are about 5 viable vendors in this space, and about 6 open source projects out there floating around. And interoperability between vendors is very good. IMHO.
