I was told that Jitsi could run on a seperate server and that Jitsi Jibri allows you to live stream and record. By putting Jitsi on your own server you could essentially change stuff in it like buttons and the Jitsi watermark in background. The Credit system is ok for an admin selling their own content but there's no way someone can send another user Credits. 

If you are going to rent a server to run jitsi, then you may as well rent a dedicated server and get off of the limitations you are seeing on UNA Cloud.
