One I’m using a lot is a self hosted password manager. Vaultwarden specifically. Useful for more than just passwords of course, can take secure notes as well. I keep it locked to my local network only, and need to VPN in to my home network when I’m out to access it.

My laptop, desktop pc, and VMs are running Linux. All of them (except the laptop) are remotely accessible over the local network via Moonlight game stream using Sunshine as the hosting software.

I use USB/IP to send things like a Dualsense controller, or USB headset over the network, as well as my yubikey if I need to log into something with FIDO2 authentication remotely. (I haven’t tested my yubikey over usb/ip yet but I will eventually) I’ve also managed to use my racing wheel this way but if it lags it hurts the game badly.

Webcam / headset / USB storage devices / game controllers work just fine so far.

Usbip, I’m learning how to build a Python GUI by making one for usbip bind and usbip attach.
