Control 2 PC's with 1 mouse/keyboard - Simultaneously

[badogblue]

So I need to control 2 separate PC's which are beside each other but on different networks with 1 mouse/keyboard simultaneously.

I've looked at software like synergy or input director but they both require that all PC's are on the same network and only the latter allows simultaneous control.

Hardware wise, a kvm switch is not suitable as it doesn't allow simultaneous control of both PC's.

Any suggestions, at the minute I'm out of ideas?

I use one of these:

UGREEN USB 3.0 Switch, 2 in 4 Out Put USB 3.0 Sharing Switch Box Box for Mouse,Keyboard,Scanner, Printer with 2 pcs of 1.5m USB 3.0 A to A Cable

£16.99

Thanks, but that won't work as it's a switch.

I need to control both PC's simultaneously (move 1 mouse to move cursor on 2 PC's)

I suppose you could use software if both both machines had more than one network card, just setup your own mini subnet for the purposes of the software and have your original network cards on their own subnets as required.

Thanks for all the replies guys, I think I've got it working using HoneyBadger's idea and Input director (only software I've found with mirror mode).

Though to keep both pc's on separate networks would each pc need 2 network cards? My plan was to connect both together with a crossover cable creating a mini lan connection for software, then connect each pc to there own unique wifi connection. You think that would work? Thanks.
