It depends what kind of censorship you're trying to fight against, but we can already do that to a certain degree. You can grant other users read or write access to individual files/folders, and as long as you can reach them (their storage server) over a p2p stream (which could be over the LAN for example, or any protocol that libp2p supports) you can collaborate.
