This is talking about SMRs and not traditional reactors. SMRs still haven't left the prototype stage, but maybe they'll start to be useful in a decade's time, who knows.

I don't think system wide dark theme works without a key, although there are workarounds of course.

Do you actually need a VM for your use case? You might use docker containers or LXC instead.

Normally I use VMs for situations where a container isn't available (Windows, openwrt) or the VM is better supported (arguably home assistant).

Very low latency would be a big deal for audio. It currently ranges from incredibly high to passable, depending on implementation.

Also Windows MR, potentially.

In this case, it would be a VPN hosted on your home server/router or a VPS. A commercial VPN wouldn't help you here, although you can use it in combination.

Welcome! Consider a VPN if you need remote access, unless you plan to share it publicly with a lot of people. It's a bit more work, but safer than directly exposing your PC to the internet.

There's definitely more Plex apps but I'd suggest just getting a third party streamer if your TV doesn't have a Jellyfin app (which suggests it's probably quite out of date and probably not the best option).

you’d still have a loss of quality due to transcoding to a format your client supports.

If you have a fast network you could transcode to high-bitrate h264/h265 etc, which would have some quality loss but probably less than using h264 directly (due to Youtube's aggressive compression).

But I'm not aware of anything that ties it altogether either, especially if the OP needs browser support.

If your public IP is in the 100.64.0.0/10 range, then you're behind a CG-NAT.

The commercial VPN client part shouldn't affect your problem if I'm reading it correctly and you just want to access your LAN remotely. If you're hosting the Wireguard server on the router, you'll likely need a firewall rule for the port used by the wg server to allow inbound connections. And you need to configure AllowedIPs correctly on both server and client.

Since you're using OpenWRT, you might try out Policy-based Routing which gives you a lot of control over this and also has some instructions for various server and client configs which may be helpful.

Also, if your ISP uses a CG-NAT you won't be able to do this without another publicly accessible device, although some ISPs will disable it if asked.

virt-manager also works over the network, particularly if you just need something basic to keep you going. But you'd likely still need to use SSH/CLI for non-VM related management anyway.
