The Internet has a back-end. You cannot physically force the products you sell through the narrow wires and small computer terminals that form the Internet and e-business infrastructure. There are, at the back, pesky things like manufacturers, warehouses, the Postal Service, and real human beings, who are involved in making it really happen. The Internet has a long way to go. The bandwith isn't there and with the mish-mash of legacy systems, it will be a long time before we get true integration.
