A data stream is transmitted to groups of individuals making separate
requests for the data stream. The groups may be arranged by placing a
maximum number of requesters in a group or by grouping the requesters
making requests within a discrete period of time. The individual
requester may be shifted from group to group or from a data store to
another data store location to change the location in the data stream
from which the data is sent to an individual requester or the time of
transmission of the data sent from the data store.
