Hi Roman,
I sorry for the delay in my answer, but I needed to set up a minimal
tutorial to show what I am working on and why I need a feature like the
one I am proposing.
Please, have a look of the README.md page here:

Inter Process Networking (PATCH):
This patch adds a new address family for inter process communication.
AF_IPN: inter process networking, i.e. multipoint,
multicast/broadcast communication among processes (and networks).

Andi, David,
I disagree. If you suspect we would be better using IP multicast, I think
your suspects are not supported.
Try the following exercises, please Can you provide better solutions
without IPN?

Exercise #1.
I am a user (NOT ROOT), I like kvm, qemu etc. I want an efficie
I have done some raw tests.
(you can read the code here: http://www.cs.unibo.it/~renzo/rawperftest/)
The programs are quite simple. The sender sends "Hello World" as fast as it
can, while the receiver prints time() for each 1 million message
received.
On my laptop, tests on 2000 "Hello World"
Some more explanations trying to describe what IPN is and what it is
useful for. We are writing the complete patch
Summary:
* IPN is for inter-process communication. It is *not* directly related
to TCP-IP or Ethernet.
* IPN itself is a *level 1* virtual physical network. IPN services

Obviously I meant:

Inter Process Networking:
a kernel module (and some simple kernel patches) to provide
AF_IPN: a new address family for process networking, i.e. multipoint,
multicast/broadcast communication among processes (and networks).
WHAT IS IT?
---
Berkeley socket have been designed for client serv
that eliminate both problems. With this patch
misc allocates the entire major 10 and avoids the deprecated call.
These are just my 2 (euro) cents, I hope it can be useful.

Dear Kernel Developers,
I have seen that drivers/char/misc.c already used the deprecated
