And another concern that came up is you might need resistors on the PIC's GPIO out to the LED's on the optoisolators, like how you always use a certain resistor to a standard LED when using TTL (5VDC).
How do I power each of the zones. Figure it out holistically on current usage by component, but I'm sure you can just use 3.3VDC and 5VDC voltage regulators (the 7405 being typical for 5V) direct off of the 7.2 VDC zone. (You might want to soften out any spikes through with some mid-value caps though just to be on the safe side.)
