Redstone Cable and Redstone Terminal: multiple redstone signals in one path

The Redstone Cable and Redstone Terminal would help eliminate redstone interference in complex redstone circuits. Redstone Cable, crafted with redstone dust and some other material (redstone dust being the conductor and the other material being the insulator), would be placed and connected similarly to rails but in three dimensions. The Redstone Terminal is a block that would be placed at the ends of the Redstone Cable. The Redstone Terminal would have one face that connects to the Redstone Cable and five uniquely textured faces for transmitting redstone signals. A redstone signal being input to one face of one terminal would be output on the matching face of the terminal at the other end of the cable. This would allow five redstone signals to be transmitted simultaneously in one line of Redstone Cable, each being input and output on one face of the Redstone Terminal. Signal attenuation would logically be less in the Redstone Cable than in just a line of dust. Maybe signal strength in Redstone Cable would degrade by one every two or three blocks instead of every block.
