What if you were able to dye Redstone, and have them work as a separate line. E.G: you have a two paths of Redstone dust next to each-other, and they connect and share the same signal. But if you dyed one of the paths, they would have a separate line, and could carry a separate signal.

I wonder if this would be useful in any way? What could you do differently, or make more efficient with this capability?
