Unfortunately, Syncthing only supports a subset of what Bittorrent Sync does:

- There is no tracker/relay server infrastructure. As a result, Syncthing doesn't work if two peers are behind a firewall/NAT without uPnP or manual port forwarding. The number of peers behind carrier-grade NAT is only growing (IPv6 migrations) and if you are often on the move (hotels, etc.) you have no control over the firewall.

- Syncthing does not support selective sync yet, let alone with the ease of BTSync where it is a Finder/Explorer extension.

- Syncthing does not support link-based sharing, which is handy if you quickly want to share something with family/colleagues.

- Syncthing is too hard to set up for most family/colleagues.

tl;dr Syncthing is great for synchronizing two machines on networks under your own control, but it is not a nearly-complete P2P replacement of Dropbox like Bittorrent Sync is.

Yes it does, it uses local discovery to find the nodes.

> Syncthing does not support selective sync yet

Yes it does, but admittedly it's not user friendly.

Sorry, I didn't formulate that clearly: two peers on different networks without uPnP or control over port forwarding.

Yes it does, but admittedly it's not user friendly.

suggests otherwise. .stignore is not the same as selective sync, but more akin to BTSync's .sync/IgnoreList, it allows you to not sync files at all.

Selective sync means that e.g. all peers have file X, but you don't want to synchronize it on your laptop because it is too large.
