I try to show at https://www.youtube.com/watch?v=M8dqgqO4TuI starting
at 9:30 how to stream data from GNU Radio using ZeroMQ
publish/subscribe, in my case to external Python software which could
very well be remote if the IP address is not 127.0.0.1, but will be
even easier to implement if the client is another GNU Radio flowchart.
I am currently doing exactly that: recording on a Raspberry Pi and
streaming to a more powerful computer for processing (again from a
dedicated Python script rather than another GNU Radio instance, e.g
around 45 min of that video).

Best, JM
