I could see Seafile being an option. I don’t recall why I discounted it before apart from server load doing the delta calculations (I was/am running it on an anemic little HP Microserver currently), but I am quite happy with NextCloud apart from missing LAN sync (which I understand Seafile supports). I got used to LAN sync with Dropbox, but when I booted Dropbox… well, let’s just say if I am setting up a new box I want to sync, I prep the location a little sooner.
