It will probably never be "won" by either side. AFAIK it doesn't really 
matter which, as long as you make it clear which is actually used.

One way of doing that is using a "magic number" at the start of the file. 
That way, either method can be used to write the format and the reader 
knows whether or not to translate.

There are other options, though.

> international agreement on using big-endian probably would be good thing
