How can i control several PCs with one keyboard AT THE SAME TIME? I dont mean switching between them, I mean sending the exact same input to all 4 pcs. Like, if i press F2, all 4 PCs will respond to it at the same time on all 4 monitors, etc...is this possible??

Hey Arislan is that anyway possible..i don't think so !! anyways lets wait for some more inputs from the real techies !!
