Ah, similar to Amazon's "shopping cart," the shop could provide a physical cart (imagine a cross between a baby stroller and a faraday cage) to help customers carry inventory to the exit of the store.
They should come up with a way of tracking what pictures people look at and then shipping the stuff in the pictures to the warehouses near those people. I bet you could do the picture tracking thing with an ActiveX control. That wouldn't work in Navigator, of course.
It seems more realistic to transmit the pictures using CD-ROM technology: it's like Netflix, but for CD-ROMs. Amazon would mail you their catalog CD-ROM, and you look at a slideshow of all the products they sell. Then, when you decide what you want, simply fax your order to Amazon, and they tell you which "shop" to drive to in order to pickup your merchandise.
Actually that is pretty sweet idea.
