[WLUG] Simple IP KVM

Has anyone used or built one of these? https://github.com/pikvm/pikvm/ It looks really interesting way to get a reasonably cheap IP KVM for home use. Though with the pain of getting RPi4s these days... it's going to take me a while to actually build one. Not sure if I wnat to spend $160 for the HAT though... the slightly flaky USB dongle so I can see my home server screen when needed it's probably more than enough. John
