I'm hoping PhotoStructure solves this usecase when I add sharing in the next version. Note that PhotoStructure is focused on just photos and videos--it isn't a general file sharing solution.

I'm looking into integrating with DAT or Hyperdrive-like solutions to help make storage backups less fiddly for users.

For now, I recommend my beta users use SyncThing or Resilio Sync to get their photos and videos off their phones and on to their home NAS or computer.
