    the description sounds like a type of torrent Wi-Fi files for amateur radio? twitter for amateurs with type of message queue or data bank. so priority would go to small data files like QSO contacts up-to 140 characters 5 to 20kb .mid-size data files like image or pdf get less priority. 1 to 4 MB . with say big data files at the lowest priority. 300 MB + plus – video or interactive or multimedia content. decentralize data files would be queued up on the radio equipment waiting for a contact other radios.
    the equipment user can set the bands, size & priority of files torrenting from their radios.
    amateur radio has a lot of old traditions that maybe would be opposed to the idea of data torrenting.
    or autonomic transmitting on multiple frequencies. amateur radios with artificial intelligence.

    […] We previously talked a little about 3D printing for non-traditional (rocket building at Relativity Space) uses with Brent and Bryce a couple episodes ago. […]
