I tried to do something a bit like this some years ago for audio only. Don't ask me for the details as it's been a while, but we tried several solutions and never really got it to work. This was under Windows.
The idea was to create a wireless free space link using off the shelf wifi gear.

I wonder if you could use netcat to direct the stream from Stdout to a
network socket then use netcat at the other end to put it into the Stdin of
the remote ffmpeg.
