Another cheesy way I've heard to address this problem (instead of replacing repairing the rear glass) is to mount a 12 volt electric warm air blower aimed up/down at the glass. I would imagine just tapping the 12 volts off the rear glass to supply the blower (the blower is about the size of a third break light and can be mounted on the hatch) will be ideal.
