Darren, the sensor shift idea would be _very_ simple to implement, and because it would act just like the old fixed-in-position anti-moire filters do; i.e. globally and without any processing involved. As soon as you have to run some code over the entire image looking for specific patterns you've got power-robbing CPU work, image pipeline slowdowns, etc.
To implement the sensor shift idea, you could drive the sensor motors with a single full sine wave each, with the X and Y signals 90 degrees out of phase. This is just like driving stepper motors (a technique I used to develop way back in the 1980's when I worked for an office automation company designing daisy wheel printers). Sending these signals to the sensor shift motors would cause the sensor to describe a small circle. Mechanical gaussian blur.
