The major use case for this seems to be where multiple people upload fairly similar versions of the same file. This approach might be interesting technically, but I don't think this is useful for many real-world use cases beyond piracy.
Actually, there are *plenty* of use cases beyond illicit file-sharing. I'll give you one: In the realm of remote data backup, this is *highly* useful, because people often move files around, rename them, make extra local copies, etc. None of that will be optimized away by rsync (each copy and rename has to be uploaded from scratch), but virtually all can be detected with a SET-like approach. Of course, people also tend to email work documents around to each other, and each recipient also might save the file and back it up, and then the savings that an approach like this brings really start to show.
