As someone who hacked together two PiKVMs based on the (now unsupported) Pi Zero W software and loves them to bits, I have been looking at more modern alternatives, and the SIPEED NanoKVM seem really nice–except for these (fixable) issues, of course.
I expect to get my hands on a couple eventually–shipping costs are a tad outrageous at the moment, though.
