Q: Using INT interrupt line on PCF8574 I2C 8-bit IO-expander on Bit-banged RPi GPIO?

I am planning to use a triplet of RPi GPIO pins as an additional bit-banged I2C bus on my RPi. This will be run at a lower than typical rate (and level-shifted via a 3.3 to 5.0 V I2C shifter unit) so that it can work over the distance necessary to be the back-bone for a Home Automation control b...
