Hi,
How can one implement custom header network protocol.
I mean header that wraps regular network packets like ethernet, udp, tcp,
etc...
The sending of this custom packets is done between processes running
locally.
ie. I get a Ethernet packet, inspect it, then add my custom header and
forward
it to another process that listens to a socket, and expect to get data
wrapped with
this custom header.

What is a good way to go about and implement this thing?

Have you looked at the tun/tap drivers?

Also, try asking this question on a network specific list.
