    interesting... (seems related to direct crypto messaging rather than
    encoding audiovisual file types and transport encryption issues) and
    thus: a billion people who want to exchange digital text files (~1
   kB).
    in a FedEx approach to transport of physical media, this is assumed
    to involve 1 billion separate "harddrives" or other disks for digital
   files
    that are going to move from one location or user to another, elsewhere
    so a billion 'packets' that need to be packaged in FedEx folders, have
    addressing and routing information attached, though firstly removed
    from equipment and then lastly reinstalled in other remote equipment
    to complete the data exchange.
    could a billion people feasibly call FedEx up today and go through
    this process of taking drives out, etc., and have the packages arrive
    ("today" in analogous terms, though 'next-day' is the gimme here)
    where the delivery is successful, no hardware failures that require
    automatic resends- likely instantaneous for packet-switch though
    for courier this could be a week span or more, to figure issues out.
    so out of the blue, a billion packets injected into the delivery
   stream
    of FedEx to arrive same-day or next-day, successful, to another
    billion addresses else some large majority (some packages go
    to the same address etc. and congestion/traffic issues with that,
    in that there may be a limit to what local resources are available).
    i would assume -no- this could not occur without denial of service
    or delay within routing or existing delivery schedules, and likely is
    beyond the daily tolerance level within the given bandwidth available,
    and to do this day after day would crash the FedEx delivery system
    perhaps because it is not designed or capable for 'data' delivery in
    the sense it may be unique from 'material' delivery of physical stuff
    versus used as a communication system for relaying messages

    (understandably this correlates with list messaging likewise)
