Taking a quick look at the site it does seem like some of the motorized options might be by Somfy based. Some are controlled several times per day, and i don't want to do that manually. I personally want mine controlled by my home automation system.
You can buy cheap motorized blinds if that is what your after. I use there RS232 interface connected to my Omni. Somfy makes many home automation interfaces. Plan on paying about $200 - $300 extra per blind for motorized Somfy blinds, at least wireless, so this may double the blind cost, depending on what you buy. Somfy has wireless remotes to fit in an outlet box as well, for a more installed look, but I really like the wireless handheld remotes. Again, using remotes is another argument for wireless. If I want to adjust it, I just grab a nearby remote. I also went with wireless remotes which i have hanging by each window. The control is all wireless, which is the way things are going, so I wouldn't terribly worry about control wiring. Personally if I could have done any prewire it would be to add 120V outlets next to each window.
