I'd rather have two dishwashers and an automated loading/dispensing system built into each one. The dishwasher is already a fairly optimal dish storage device. Using somewhat standardized dish dimensions would make it fairly easy to implement.

I wish my kitchen was that big, but even then I think I'd prefer to have my plates stacked. Sure the ones my family uses every meal may as well live in the dishwasher, but I have a few more because once in a while I have guests (or they break) and I don't want those to have the empty space between them the dishwasher needed.
