    Fair enough.  There is an RFC for transmission of IP datagrams with
    avian carriers (avian==pigeon).  There is also at least one
    implementation visible on youtube.  That does not use electromagnetic waves.

    IIRC the RFC with IP on avian carriers was an April's Fool.  It can be a
    subject of joke.  

Like most April Fool's RFCs, there was truth to many aspects of it. Although nobody expects an efficient network based on pidgins, it remains true that the symbols used in an Internet implementation need not be bosons.

    In that sense, it can be a serious matter to write an
    IPv6-with-AvianCarriers I-D that takes into consideration an IPv6
    address of the pigeon.  Sending a packet in that way: source -
    intermediary - destination, each having an IP address, could be a novel
    paradigm in the Internet, which is used to source-destination only.

Avian carries does not introduce an intermediate address at the network layer. Its addrsses would be no different to IP than are Ethernet addresses; they represent the link addresses.

Additionally, IP isn't source-destination only; both IPv4 and IPv6 have 'source route' options.

    Further, it can be considered that the data carried by a pigeon would be
    encrypted, and if that used a quantum-resistant algorithm then we had an
    approach between quantum networking and avian carriers.

This group and discussion has been focused on quantum systems, not quantum-resistant classical systems.

    This is entirely unclear to me, I dont know(?)

    I thought, really, that quantum communication did not involve
    electromagnetic waves at all, but some other way of transmitting data.

Photons are EM waves.

And the "classical communication" I'm referring to is the classical network used to coordinate the quantum one, i.e., to exchange basis pairs, coordinate bell pair use, etc.
