Content-addressable storage
====================================

 - Pretty cool, many unusual properties when compared to normal filesystems etc
 - If you have the content you know the address. If you have the address, you know what the content should hash to.
 - Used by most distributed file-stores and many filesystems
 - Immutable (in the sense that a file can't be updated, a new one is created)
 - Can give de-duplication for free
 - Helps with syncing and "multiple writers" becasue there's no chance of overwriting data
