Want to run two computers with single mouse/keyboard simultaniously (no kvm, or senergy)

I know this sounds crazy, but im needing to run 2 computers with 1 keyboard and 1 mouse so that i can enter command codes to both sytems at the same time.(i.e. not switching with kvm or using senergy)

i know sounds crazy but with the amount of information what i need to do it will save me loads of time.

no cut paste or networking hacks either please. I am looking for physical hardware options.
thnx
Gustav

I highly doubt anything like that would work. Each computer will be fighting for control over the mouse and keyboard, and with different inputs and the same output to each computer, it will mess everything up and simply not work.

The best way to do it is through a network program. They have programs that teachers and network admins use to update and send information to all the computers at once.

It won't work...you would have to network them and be able to use remote desktop to use both at the same time.
