pipeProcess will give you the input/output pair (and believe the 
output is accessible at the available time the program writes a 
line). To publish the same input to multiple pipes will be 
something have to create along with a receiver of multiple 
outputs.

That is to say, you can do it, but managing read/write is on you.
