@corysimmons getting other nodes to hold your content is an out-of-band concern for the IPFS protocol. There are a number of tools evolving to handle this. For example, you can use ipfs-cluster to form participating networks of nodes who share a pinset. Alternatively, Filecoin will allow you to pay the network to store stuff for you.
