I don't really care about 3D but this glasses free tv tech gets me wondering whether it's possible to do glasses free simulview or multiview. I know it works in car nav systems, driver sees sat nav, passenger can watch tv on the same screen. Why not do it for tv's, upto 4 different programs simultaneously, together with directional audio speakers.
Or 2 way 3D on each side with surround audio remixed to the left and right side of the room for each program.

I wouldn't know anything about that stuff, but I'm sure it'll be doable sometime down the road. The question is whether or not it'll be practically and worth mass marketing.

I've been looking but I can't find much on how Dolby 3D actually works and whether it will be compatible with displaying different sources at different angles. They only say that it can generate multiple position adjusted views, upto 120 in total, depending on the display.
Some techniques focus the same pixel into many zones, that wouldn't work for discreet views. (nor would dolby 3D make sense)
Other techniques have discreet pixels per viewing zone, that could easily be used to show different content, but at the cost of resolution.

Maybe this new electronic lens technique can switch between both methods.

That's from 2011, maybe that's ready for production now.

Anyway as you said, will it be marketable, how much more will it cost.
They already add it on to polarized and flicker glasses 3D tvs, but wearing glasses to watch 2D content is even worse.

Flicker glasses have the option for 2 simultaneous 3D views already.
