I did a little work to get a rough implementation in Python, and it appears
you are right. The result is a file compression algorithm which allows you
to add free space to your filestore by creating new files. This has led me
to speculate that most operating systems could really use negative
filesizes.

Is your disk getting a little full? Just md5lzip your largest files and you
create free space on your disk!

I'd like to thank Moshe Zadka for making his original code available to
facilitate these experiments.
