The official web page for the Comet literally says right at the top, “Remote KVM over Internet”. And goes on to say that it “lets you control a computer or server from anywhere, as if you were sitting right in front of it. Imagine you're traveling, but you need to access and fix a computer at your office.”

The Kickstarter page for the JetKVM says, “Free & Optional Remote Access: Remote management via JetKVM Cloud using WebRTC. Secure and a fast direct connection, even behind the most restrictive NAT environments, with our STUN and TURN servers.”
