Cached HAXML on a HASP gateway or some equivalent could more than satisfy your concerns. Devices that are defined and controlled by such technologies are being built and deployed today to create smart / connected buildings (and soon residences). If you were to study this, and recast your business strategy accordingly you might be surprised by the opportunites that present themselves to your company.
But please don't try and convince me to embrace your flat world thinking. You and the HA industry are being majorly disrupted, you just don't know it yet.
Unfortunately, I'm trying to make an informed (purchasing) decision in the middle of this disruption. I'm all ears if you choose to offer some fresh insight on that subject.
The issue isn't whether the stuff inside a building can be controlled from outside the building. We've all been providing such capabilities for a long time. But the issue here is controlling the building from inside the building. You've not addressed the point I made. What possible benefit would there be to moving any of the automation system out of the house? There is none that I can see.
Unless you can come up with some reason why having any of it outside the home is better than having it inside the home, you are kind of just coming off like a jerk by failing to do so, then acting like we are cave men for saying otherwise.
As I said before, the only thing you could move outside of the house is the controller, and it's just a tiny piece of the pie, and it would gain you zip to do so. And in return for no gain, you are now dependent on your internet connection to operate your home, something no one is going to do, and you increase the latency of all operations, where latency is already a big concern in any automation system.
So, before you start implying that everyone else is stupid, you may want to deal with the fact that you write white papers about clouds, and these folks all actually deal day in and day out with real people in real homes with real automation systems. Unless you can come up with some legitimate advantages to what you suggest, you are just coming off like a jerk.
As to RS-232, there's actually a lot to be set for serial communications. It's a point to point system from the controller to the controlled device, not a shared medium, and it's plenty fast enough for the devices it controls. In most full bore automation scenarios most of the important hardware is in the same room anyway, so distance isn't a problem within the automation closet really. So it's actually a quite robust means for controlling devices that cannot be interferred with by some other device doing something dumb.
It's biggest problem of course is that it's a fairly complex standard with a lot of variations. But of course IP is as well, and most end users are as incapable of spelunking networking problems themselves as they are figuring out serial cabling.
So, though I'd not cry to see serial go away, it would actually be nice to have some more modern version of it available for automation type needs, i.e. a simple, robust point to point connection. The network is great, and it enables lots of stuff. But it's not necessarily always the most optimal thing for everything to go through it.
