Metavision Pipeline and IPC (Interprocess Communication)

Metavision Pipeline and IPC (Interprocess Communication)

Hello, 
I can't get my head around how to make C++ Pipeline work with IPC (NamedPipe for example).

I am interested in both directions: 
  1. sending some data to another application.
    The most fitting to the Pipeline probably would be "SenderStage", similar to the LoggerStage from the tutorial, but that will send data, instead of printing to console.
  2. receiving data from another application. 
    The minimal example: keyboard input from the console of an     another application would change some parameters of some stage, similar to metavision_generic_tracking, but console input from another application.
