I can't tell if you talking about the order of bit in a wire protocol, or endianness of multibyte memory allocations. For memory endian-ness is essentially arch determined by cpu reads, so its arbitrary. Little endian has the advantage of sharing addresses of narrowed conversions. But the difference is holy war iirc. For wire protocols, it seems like the natural ordering to me.
