I wanted to see how much latency there was with the JetKVM's feed (answer: not much).

Unfortunately, it's not ideal for this:

• The Switch doesn't recognise the passthrough keyboard (so I used a long USB extension and a wired controller)
• There's no audio
• I tried it just before parental controls kicked in, kicking me off (now I know how the kid feels)

There's a write up at https://www.bentasker.co.uk/posts/blog/general/my-jetkvm-ip-kvm-is-here.html
