rolling tables

I love the idea of being able to move your kitchen table with just the push of a finger, by having all rollers on all the legs. Wouldn't it be a fun way to present appetizers to guests--just by rolling it right on in the room? Or if you wanted to move from the kitchen to the family room to be close to the fire while not having to pick up and move all your plates and wine? Can you tell I really like this idea!?!
