Authorization access controlled content exchange can be implemented, for
example, in a multimedia content distribution environment when individual
client devices are capable of storing content. A content index is
maintained for each client device that reflects the content stored
thereat. Predefined authorization access information for each relevant
content item may be included in a content index entry corresponding
thereto. A profile is maintained that includes predetermined
authorization access information which indicates access rights. A search
may be performed by and/or on behalf of a requesting client device for
desired content with reference to authorization access information. A
content transfer to the requesting client device from a target client
device may be enabled if the predetermined authorization access
information comports with the predefined authorization access
information. Searches may be orchestrated or effectuated by the
requesting client device or a head end of the multimedia content
distribution system.
