DESCRIPTION ^

This is an attempt at solving a problem with hosting millions of static files. It should be straight forward enough to take a suite of n servers and store x files across them.

It is assumed that each bucket is publically accessible and that the disks may or may not be. It is non-trivial to add a bucket later.
