Is it possible to add dumb storage as a sync target?

I am wondering if it is somehow possible to add an ssh or samba server as a sync target. Obviously, two of those couldn’t sync because neither is active but all the other clients could sync to one. Is this supported?

You might be able to add a mounted SMB file system as a folder. Syncthing itself has no built in support for remote file systems though.

Too bad. But thanks for your answer @calmh!
