It is meant to be particularly good at preserving and distributing data. Thats why the FS came there. So no, you can't do "live stream", but "past stream" file you can seed from a home line and it will migrate to the node(s) closest to the subset(s) of recipients. And will stay there as long as the policies say (usually as long as there is a free space for newer content).

@ohir @alienghic @Andres4NY @KathyReid Pragmatic General Multicast is a special case; it streams, yet if implemented fully, it has provisions for some store-and-forward for error recovery by downstream leaf nodes/hosts. The financial traders sometimes employ a flavour of it; what was formely called 29West Latency Buster Messaging (LBM) was basically just PGM with knobs on. Older Cisco IOS releases implemented PGM, there is open source floating around out there, probably ZeroMQ best source now.
