If it's a good idea then please consider this intellectual property.It's easy .. the zeros are fatter than the ones.no no no.. it's simply, since the OP posited a math solution, md5. ship the size of file + hash, compute file on the other side. All files can be moved anywhere regardless of the size of the file in a single packet. The solution is left as an exercise for the reader.
You would need a lot of computing power to generate a file of any decent size. If you want to be evil then you could send just a md5 hash and a sha512 hash (or some other hash that would not have a collision at the same time except when correct)
