"Broadcast" is not to be seen in the strict and network-layer oriented sense. NNTP is being (ab)used for binary distribution, it carries data regardless of whether this data has been requested or not. Call it broadcast or multicast, doesn't matter, the traffic is there even if no-one is listening. That's quite different from a request -> serve structure with distributed caches (HTTP can do that, with squid e. g). -- Matthias Andree
