In a few years, $100K systems will be $1K; a few years after that, $100.
And some of the people here could help make it happen. (What if digital picture frames or pocket-size projectors had auto-focus, auto-pan cameras, and however many you positioned in a single room auto-configured themselves for optimal telepresence effect? Etc.)
So it's a valid suggestion from a speculative perspective, even if we know a single home worker isn't likely to buy one of these top-end systems today.
The tech is awesome, and I've used HP Halo rooms, but they really aren't meant for home deployment. There's just too much physical setup needed (aligning cameras, tvs, etc) that I doubt it'll ever work for that purpose.
