I think one of the interesting use cases for IPFS is having a distributed build store for tools like Nix and Guix. It sounds to me like almost the perfect case for it: an immutable datastore of hashes of reproducible builds is well suited to distributed storage. Imagine being able to peek into a global store of build outputs and, for the hash of any given inputs, retrieve some corresponding output. It would be an incredibly unique experience.

There’s a proof of concept of building IPFS into Guix’s store[1]. There’s also periodically discussion on the mailing list. I’m sure it’s much more complicated than I’m giving it credit for, and there would be security and social implications (someone’s going to be building most of the software, and what happens if you have low bandwidth or a small data plan?) Still, IPFS sounds like an interesting experiment in this area.
