Dunno about ideal, but it should work.
It does have quite a bit of overhead, meaning it’s not the fastest out there, but as long as it’s fast enough to serve the media you need, that shouldn’t matter.
Also, you need to either mount it manually on the command line whenever you need it or be comfortable with leaving your SSH private key in your media server unencrypted. Since you are already concerned with needing to encrypt file share access even in the local network, the latter might not be a good option to you.
The good part about it is, as long as you can ssh from your media server to your NAS, this should just work with no additional setup needed.
In your case, instead of getting a dedicated server and putting proxmox on it, I would check if it might not be cheaper to just get individual virtual servers directly.
Other than that, sure, I have been a customer for many years now, and I have always been a fan of Hetzner’s price to quality ratio.
It’s odysee, a frontend to lbry, a sort-of decentralized alternative to Youtube. Which seems very enticing, because an alternative to Youtube is badly needed.
Unfortunately, at the moment it is completely overrun by religious nutjobs, Nazis and other assorted scum. It is not by its nature an alt-right service, but it does attract all those who would be banned anywhere else.
I can see it going both ways. Talking about execution times, this would be an exaggeration, but then, these memes always are.
