/usr/bin/nc: cpi

This band (netcat) is wickedly sick, releasing their album (Cycles per Instruction) as Linux kernel module!

The approach is pretty simple:
#include "../netcat.h" 
#define NETCAT_CPI_TRK1_LEN 624344 
struct netcat_track netcat_cpi_trk1 = { 
    .name = "Interrupt 0x7f", 
    .len = NETCAT_CPI_TRK1_LEN, 
    .data = { 
         #include "trk1data.h" 
    } 
};

It (the C header file) is actually a wavefile , you can redirect it to media player just as normal I/O operation. Just like silly "Hello world!" kprintf from kernel demo program you used to write on Intro to *NIX Operating System lecture.

Anyway, I am quite afraid there will be path issue between this netcat and the legitimate netcat.
