It provides tones more than I really need anyway, and I figured a simple raw socket send/receive can't be *that* hard. I may have to reverse engineer some C code, such as dhclient...

Yeah, I think you're working with something fairly esoteric there -
bypassing the lower tiers of support (routing etc). Chances are you
won't find any good Python examples, and C's all you'll have. Are you
reasonably familiar with C?

Point to note: Raw sockets *may* require special privileges. Some
systems require that only root employ them, for security's sake.
