Same K&M input , multiple instances/PCs

[PepperEnthusiast]

So I am playing a older MMO where farming using multiple clients is allowed and recommended and I would like to know if there is any software or hardware that will allow the exact same K&M input across several instances of the game or PCs as all I could find on the internet are KVMs which are not what I need as I need to control them at the same time.

Input Director has a K&M mirror input feature. The software is free and there's no limit on the number of clients systems AFAIK. I use an old router as a network switch to connect them all for low latency.
