SPI devices in parallel.

Dont worry about it.

I'm going to try the drivers and will be using standard cat5 cable and connectors. Makes things really easy.

Just a thought, connect a 1K resistor to the output of each receiver and connect the other end of the resistor to the base of a 3904 transistor, I think I should be able to turn on an LED each time the line goes high without loading it. It would be really nice to have a simple led showing activity on the data lines at each light, as a cable and connector diagnostic.
