You could definitely use BitTorrent sync securely for personal use, like DropBox. The issues with illegal downloading are totally separate. If you are downloading a public torrent, you join a swarm and upload pieces of it to others, where they can see your IP address. If you are just syncing your files with it, no one else joins the swarm.

But the source and destination IP addresses of each system in the swarm are leaked in the IP headers. How does the protocol avoid leaks?

I fail to see how this is any better than just using scp or rsync.
