I hope that you or someone could make this preferably with the ability to remote transfer without first downloading to local pc then uploading. Also with delete support when moving the files from putio.
PUT.io Also supports FTP (TLS/SSL) and WebDAV but those are readonly so no delete ability there.
While having the ability to directly transfer files from putio to another cloud would be ideal, putio has a feature to automatically remove the oldest files when low on space. So that can be worked with.
Still does not have the ability you wanted but we have added putio support for rclone. I have posted an announcement about beta testing if you are interested: Put.io: Looking for beta testers
