If it is conceivable that it would work for a keyboard does such a thing exist that is meant specifically for this purpose? I don't need it to support any USB peripherals other than a standard keyboard that will only be sending info one way. And It will not need to make use of any special keys such as NUM LOCK, or SCROLL LOCK. It just needs to work with sending single letter keystrokes to multiple PCs such as: "a", "b", "e" etc

There's no question it could be done, designed for a very limited application (e.g. keyboard, mouse) but I'm not aware of such a product existing - there probably isn't enough of a market to make it cost effective to produce.

"in the keyboard example, where information is being passed only in one direction" - that's an incorrect assumption: data passes both ways, at the very least on power-up/plug-in ("Hello, I'm a device" "Okay, what are you?" "I'm a keyboard" "Okay then").

@Piskvor Exactly correct - I said it that way only to simplify my point. But that is exactly the kind of simple signaling protocol that a hardware implementation could mimic. That is, the splitter cable/box would have circuits that would handle the computer side of that conversation as a mimic. It's doable - but again, not marketable.
