-----BEGIN PGP SIGNED MESSAGE----- Would using TCP sequence numbers to carry stegoed data be practical? The data would have to be removed at a lower level. This would mean kernel patches and extra system calls in UNIX. I have no idea what this would require under Windows or Mac. This seems like the ideal place to stego data because most OS's have started using random sequence numbers. Any ideas?
