1. A method of simulated Internet-wide multicasting over a first network of machines providing ingress and broadcast, the first network associated with an overlay network, the method comprising:
receiving a data stream at an ingress node of the first network, the ingress node having been identified as having sufficient bandwidth and processing capability, and by being in network proximity to a publisher of the data stream;
identifying an egress node of the first network that either is co-located in an access network in which one or more client machines are located or otherwise advertises an anycast address for the stream, the egress node being distinct from the ingress node; and
delivering from the egress node, via multicast, the data stream to the one or more client machines.
