This is closer to a shower thought, given I don’t really know much about how ActivityPub works. Has anyone, or is it even possible to, made an instance designed to work as say a FUSE file system?
I was mostly just thinking about how hard UIs are to make and thought “what if the content was the UI”.
Correct me if I’m wrong, but I don’t think IPFS itself is tied to a blockchain. That said, the creators seem to be involved in a lot of crypto stuff (including creating Filecoin on top of IPFS), so it does have blockchain baggage attached to it.
