Desperately seeking...., not Susan but multiview LAN monitoring software

I currently run a couple of 8 port autoscan kvm's on the repair bench to monitor all the machines we get in for Virus removal.

What I am looking for is some software that will allow me to show all the screens at once on a single display and then allow me to select a single screen at the click of a mouse which will then maximise that screen.

I have seen in the past adverts for network monitoring software that shows 16 desktop images on a single pc screen but at the time didn't have the need and now I cant find them to save my life. The closest I have come is a Thai company that shows a multiview kvm which I fully expect to be price prohibitive.

Can anyone recommend a suitable application?
