Say you're building your own house and you want the wiring system to be truly upgradeable. You know you can't just put the 'latest and greatest' data/electrical jacks in it, because those too will become obsolete. I've been thinking that in my next dream home, I would want PVC pipes going from place to place connecting all the electricals. And I would also want walls or some parts of the walls that are panels, and easily removeable to access the wiring. This could be done fairly easily with paneling, actually. How would you go about it?
