1. A method in a network node configured for connection to a network, the method including:

  • the network node identifying a data file for storage in the network; and

    the network node selecting storage locations among available network nodes in the network for respective copies of the data file based on determined locality attributes relative to at least one user of the data file, the network node selecting the storage locations based on the network node having possession of a unique locality control object for the data file, the locality control object providing sole and exclusive authority for controlling storage or modifying of any of the copies by the network node or any of the available network nodes, each storage location selected by the network node being within a corresponding selected one of the available network nodes, identifiable as a storage node, the storage nodes storing the respective copies being less in number than the available network nodes, wherein the locality control object is transferrable to another network node among the available network nodes.
