Future Shopping via Multiple RealTime Variables

For me there is only one web. A website for browsing with mobile, tablet or my desktop. The Web is there to be used and I think we have only seen the beginning of its possibilities.
So far fills native applications certainly a variety of purposes (such as providing the opportunity for Apple to fill the fund) But as our browsers are allowed to take a larger part in our hardware, reduces the importance of native solutions.

Why build the same thing several times for it to be used by everyone?

One can not say that I'm the first to have that view. And I have no hope that it would feel so unique. Though it is essential for the rest of my reasoning.
Today was one of my techniques (Ulf Björklund) how he used a NetDuino to get some random data and then he showed how to filter it through XSockets. It enabled him to create some cool conditions that depends only on web communication.
I sketched a simple usecase to explain some of the opportunities this offers:

An idea of the future the store

Let's say you have a system that connects a people-counter in the entrance hall with a variety of digital screens in the store and some NetDuinos that senses where people are moving. To this you add QR codes, NFC or another opportunity for customers to connect their mobile devices.
You will receive the following variables to experiment with:

• Time of day
• Geoposition
• Number of visitors in the store
• Selection of connectivity
• NetDuino Data
• Data being sent to customers

Some of the conditions created are the opportunity to control the store's communications depending on the number of visitors in the shop or a unique visitor's position in the store. Imagine being able to send information or offers depending on time, location, number of other customers in the store and previously sent offers. The possibilities are almost endless.

But

Which is thrilling for us in the industry, but a deterrent for those who must fill the system with information and offers (read our clients - those who will pay the bill)
Here you will easily administered web-based systems in handy. Update in real time (if required). Update only one site that appears everywhere in the system.

Everything is digital so we can measure outcomes and impact (which scares us marketers though we have to do better jobs) And last but not least, we can reach all our customers while they are online. Thus, we can control their behavior! (or we hope to control their behavior in all cases).

How?

What if we could send to our customers depending on what decisions they take in the store? If we send an offer depending on the time, place and number of visitors in the store. But if we notice that the customer chooses to slip his phone in his pocket after the reading the offer we just sent (Geoposition) what would we choose to do?
Calling the customer? Send a new even better deal? Or ...
Think on. You will soon be faced with this kind of scenarios.
How cool is that!?
