I liked the idea, too. So here is what I've done so far. It work till
now for tcp but it should be no problem to do it for udp also. (Or to
do it generally for ip)

To set the sockopt you have to write it this way:
 setsockopt( create_socket, SOL_SOCKET, SO_PFTAG, tag, strlen(tag) + 1);
 getsockopt( create_socket, SOL_SOCKET, SO_PFTAG, bla, &a);
