This is already fairly similar to how high-end retail for clothing works; each boutique will have an item or two that is unique to their store, or done in a special colourway that can only be found there. The largest brands also operate their own stores already, go to any high street in a major city and you'll find LVMH and PPR brand flagship stores
I was in the market recently for a high-end camera and it would've been really bad for the OEM to have different codes for it in different countries let alone different stores because it meant it would've been too hard to do research.
The cost to the OEM would be too high to bear to appease the mom & pop store at the other end, at the end of the day they don't care who retails their unit as long as they ship more at the wholesale rate.
Apple is also a special case in that they control pricing of their goods with an iron fist and never allow discounts. The largest reason for "showrooming" as discussed in the article was the delta in price between a B&M store and online - with Apple your choice is "$cur and the product now" or "$cur and the product later"
We might also see exclusives (time and chain based), and may even see more vendor showrooms. Sony, Apple, and others successfully operate stores which give users a chance to try things out in person.
I'm very curious to see how this will play out - or if it will matter at all.
