moving house

I am moving houses a lot at the moment, house-sitting and staying in friends' spare rooms until the new rental is available. It is always when I don't have a home that I spend the most time designing a dream house in my head. One of the important questions, besides details of the kitchen (having spent too many years in cramped quarters, too often without an oven) is of course, where would all the pneumatic tubes go?

Where to put them? In the living room, at the dining table or by the BBQ, as in the Heineken commercial above? In the children's room, like the tooth-fairy dad? Between the kitchen and bedroom for night-time snacks? Between the library and couch? The mailbox and kitchen table? Let me know if you have any good ideas!
