JetKVM is much like nanoKVM but a slightly polised version.
What is JetKVM?
JetKVM is a high-performance, open-source KVM over IP (Keyboard, Video, Mouse) solution designed for efficient remote management of computers, servers, and workstations. Whether you’re dealing with boot failures, installing a new operating system, adjusting BIOS settings, or simply taking control of a machine from afar, JetKVM provides the tools to get it done effectively.
As far as I know, these Jets are not available for retail yet, but can be bought via their kickstarter.

Their FAQ says that they haven't tested this with KVM switches but that it should work. PiKVM doesn't always work well with switches, hoping this will be better. Because off-the-shelf IPKVM switches all seem rubbish, overpriced or both.
