pigpio is a good library, especially if you need lots of PWM, serial, etc. But all SIP is doing is turning relays off and on. Other than the minor security issue of running SIP as root, I don't see a compelling reason to use this library, especially since it doesn't support physical pin numbering and Beaglebone Black. Rather than fork SIP, I suggest creating a new relay plugin that uses the pigpio library instead of RPi.GPIO.
