I stumbled onto Syncthing because it was mentioned in a recent article.
Storj is a crowdsourced P2P network that allows encrypted and private storage. Very similar goals to Syncthing. We figure if the data is encrypted client side and split into pieces you can store it on devices other than your own. Since the data is stored hundreds of independent devices, and not a centralized service or server the user retains control over the data. If you would like more technical details feel free to read our whitepaper (bottom of our website).
Wanted to figure out if there was interest to integrate Storj into Syncthing. If there is interest from the community we would be happy to provide support, bounties, and/or sponsorship to help get it done. Happy to answer you might have.
