Beverage Chiller: High-End Fridge Feature

This Rapid Chiller gets good functional reviews on Amazon. 1 minute to chill to 42 degrees F, 5 minutes to 34 F. The downsides seem to be convenience--it uses a lot of ice and water.

So what if it where built into a fridge? The water could be pre-cooled and re-used. Would be a pretty cool differentiator, for high-end appliances. Would certainly appeal to me. Less need to keep a wide selection of pre-chilled drinks.
