Just a minor point: piping IQ data over TCP or UDP is actually quite
common in the radio scene. I also wouldn't be surprised if Linux gains
an API for dealing with IQ data in the future. That would allow writing
more driver-esque radio stuff.

Because radio is such a wide field, there's no place where adding it in
FFmpeg is likely to be appropriate. A demodulator could output data
packets, or bitstreams, or audio, or video, or fax images, or IQ data
etc etc. Should we have an APRS implementation in lavf? AX.25? Maybe we
should implement WiFi?

This reminds me of the IPFS debacle.
