I would like to ask for adding SCP (SSH) protocol as storage type. The reason to ask for this feature is the below use case:
Two friends decide to backup each other data in an encrypted manner and with minimal server setup. Several wireless routers (e.g. Asus routers) support remote login via SSH (with key authentication) and support attaching a USB drive to share. Upon login via SSH to the router, the USB drive appears mounted as a folder. This setup is far more secure than sharing a drive using Samba. Standard SSH server supports file copy via SCP, but not via SFTP (which requires a separate server).
