2x20 display using a i2c shift register

I want some of you input on using this chip as just the data lines on a 2x20 display.


I am toying with the idea to make my parallel display somewhat serial by using the I2C method. Any thoughts?

My display would still require me to use the RW, RS and E lines but using the I2C chip I could free up 6 I/O pins on the propeller.
