I wouldn’t mind the “host” byte order, assuming it just means use sys.byteorder. I think I have done this a few times, both when I really wanted the native byte order, and when I didn’t care, but assumed the native order might be slightly more efficient (e.g. bitwise arithmetic on 512-byte blocks).

But I don’t understand the point of “net” byte order. Wouldn’t it be the same as “big”?
