Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

well, that is an example of how simple it is if you can do it with shell.
is the communication two way or one way?
well assume it's two way you must have two FIFOs per pair,
parents read/write child write/read which is 6 pipes.
but then the parent will probly need to use select to check which is ready.
(A pipe can only connect with ONE reader and ONE writer at a time)
or, you could have one pair of FIFOs and say use the PID of the child as an
IP address as it were to prepend each message,
is this homework?

an interesting use for a FIFO often seen in books, is for your
mail .signature file (if this applies).
you replace it with a FIFO and a serving process that gives a
random quote (often the fortune program) every time the
FIFO is read, nifty eh?
