The nozzle's that the VCN-2000 kits uses are not special. They are a standard AN-4 connection on the back of the nozzle and you run a standard AN-4 SS line to the valve. I know its computer controlled, but the nozzle itself has nothing to do with the computer.
Here is a nozzle from NOS. It looks exactly the same as the one from Venom, just a different color. Get 6 of these, 6 lines for it and a distribution block and your ready to go.
P.S. I am not upset; I have just installed that system about 6 times.
