make a mount to one of the cloud solutions ( acd, gdrive etc… ) which have encrypted
make mount with unencrypted cloud content
behave as cloud provider with encrypted drive
clients
mount unencrypted drive from master server ( with read only )
For my particular case the idea is to allow people to setup their own plex servers that are connected to my library without giving them direct API access to my drive and as well encryption key etc…
This will be difficult over the internet. It is easy to make a mount. But how would you share it out so that plex users can access it? This is a plex limitation. Plex server likes local file systems which means you’re limited to NFS or SMB. Those are pretty insecure and not great with latency involved which means you’d need to wrap one of those over ssh and I think you won’t be happy with the performance.
This is all a plex limitation though. I do similar to what you are asking for but I use a better streaming medium. I use a nginx https server to share out my data. I use KODI which allows https sources though. People simple add the https source to their kodi installations and its done.
Thinking a bit further. If rclone supported 1) webdav(s) then you could mount the https. I think there is a issue for that OR if rclone ran a daemon mode where rclone could connect to rclone then you could also use that path to share. I think I also saw an issue for that.
