You are defining the geofilter, but not using it. Try doing "reverse_proxy @mygeofilter mydude:8096"
Check out distrobox. Basically podman or docker containers, but automatically more integrated into the host system. GUI programs work pretty much out of the box with it.
Headscale is pretty light on resources, especially since it doesn't come with a webui (there is third-party ones like headplane you can use though). RAM usage is like 70mb for me currently.
If you want to have more control about it and become independent of the SaaS offering, you can even selfhost headscale, a FOSS tailscale control server. I run it myself with zero issues.
Maybe Tailscale could be super useful for this!
On Arch+KDE Plasma it's nearly perfect for me with a 3070 RTX
Qemu can emulate one architecture on another. And qemu-user can be used to run a single userspace-program on a different architecture.
Maybe something like Elvish or Nushell could be worth a look. They have a lot of similarities to classic shells like bash, but an improved syntax and more powerful features. Basically something in between bash and Python. Not sure about disk footprint or general availability/portability though
