I also have an idea, it concerns Killy's memories at the beginning of LOG 50. there was Domo and Iko, and definitely they were not in the Megastructure. does it mean that all who die in the real world continue to live in the Netsphere somehow? (but in next to last LOG contains conflicting information) or maybe they knew each other before?
again, if the first suggestion is right, the Netsphere is a kind of Heaven. so, all(as long as all will die sooner or later) go in Heaven... except Killy. He is immortal... poor guy.
