DAW control without kvm

Hello! It's my first post (that will not be the last one...) in this useful website! I was wondering if I could make a simple patch with video/keyboard/mouse? I wanted to use db25 to make things easier and make my own pin-out (I must admit i never did db25 cable...). It maybe will take time but do you think it's possible? I will have something like 3 computers / 6 screens for three commands. To be clear the patch would be like that: sources - pc1.1 - pc1.2 - pc2.1 - pc2.2 - pc3.1 - pc3.2 sources - pc1.1 - pc1.2 - pc2.1 - pc2.2 - pc3.1 - pc3.2 destinations- post1.1 - post1.2 - post2.1 - post2.2 - post 3 The post3 has only one screen. I made 2 sources lines for distributing. The lenght of cable is not a matter. Thank you (sorry for the froggy english, too!) Your advice is really welcome!

You can either use a program called Timbuktu, and a laptop to control your DAW, or use a unit called the Tranzport to achieve the same effect, which is made by Frontier. But I'm afraid I don't understand your PC routing very well...
