Imho it&#x27;s also worth to mention that bittorrent sync (<a href="https:&#x2F;&#x2F;www.getsync.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.getsync.com&#x2F;</a>) follows a fantastic concept with huge potential.<p>Unfortunately it&#x27;s not open source but alone the fact that it can run on a peer to peer basis without the need of any external out of control cloud host is very appealing to me.
With small devices such as raspberry pi or NUC becoming more powerful the approach has a bright future.
