A method comprises distributing a plurality of descriptors of file encoded with comprising a plurality of recipient nodes, wherein at least one descriptor is distributed from the first node to each recipient node of the at least a portion of the first group. The at least a portion of the first group communicate their respective descriptors received from the first node to other nodes of the first group. A system comprises an origin node operable to distribute all of a plurality of descriptors of a MDC file to a first group of recipient nodes, wherein the origin node does not attempt to communicate all of the plurality of descriptors to all of the recipient nodes of the first group. The recipient nodes of the first group are each operable to communicate a descriptor that it receives from the origin node to other nodes of the first group.
