networks for fire-and-forget secure reliable files, file requests, Internet

encrypted, explicitly authenticated by known participants public keys.  Onion
encryption is applied to relayed packets.  Each node acts both as a client and
server, can use push and poll behaviour model.  Multicasting areas, offline
