Human explorers have discovered that Pandora is home to a highly valuable resource, "unobtainium." Because he shares the DNA of his highly gifted and well-trained brother, Jake Sully gets ownership of the healthy body of a Na'vi. He has been ordered to use this body for military reconnaissance, but there's also an altruistic science team (headed by Sigourney Weaver, who also has an avatar at her disposal) that Jake is supposed to answer to.
In Avatar the network (called "Mother All") exists within the planet of Pandora. The Na'vi have a special relationship with their planet accessed through a network cable that shoots out of the back of their heads (covered by a braid). This allows them to plug in to their environment, a variety of animals, and to each other.

Jake Sulley's desires are finally satisfied when he passes from human to Na'vi, from the gnostic imaginary to a fully present hyper-reality. Unlike the rest of his naive species (who have done everything in their power to attain "unobtainium"), Sulley leaves behind this sort of organized desire and is immersed in a new world where desire is realized in the natural network of Pandora. As Graham Ward writes in Cities of God, "The gratification of human desire comes in the experience of the presence of the present. There is no remembrance in cyberspace, only a memory bank for the retrieval of arbitrary pieces of information."
