Not exactly full "IP KVM" and missing the VM part, BUT for basic screen access to say a server or scope or whatever with a VGA output, those dirt cheap "VGA to USB" converters found all over Amazon etc., can do a semi decent job as well. Not as good as gold standard VGA frame grabbers, but they present as a video device so they are supported out of the box in every major OS. There's always one or two in my kit bag. So much better than pushing a monitor on wheels.

The article covers a range of "new" KVMs but doesn't even mention the staples used for decades like Avocent, Aten and APC. When I ran or built a lab, we'd always have the key systems on KVM but always three or four "swing" adapters on long runs of cat6 to reach anywhere in the whole room. Lifesaver.
