From the readme: "It uses Linux system calls to interface with the network stack, which makes the code unportable across platforms, but keeps it completely libc free." Were you expecting it to program the NIC directly? It's better to leave that up to the OS and drivers. I agree with you about the novelty of this app, despite the well-commented assembly code, it would be much shorter and more readable in C.
