Yeah at least 3000 if ambient lighting is involved.
I was trying to find a cheap $200 alternative to get some effects showing in a 140" diagonal area like in the video.
That BenQ you linked gives off 64 fL at 80" which is a pretty bright image, more then sufficient to show detail on irregular walls with ambient lighting, and enough to compete with the tv for attention.
A 4000 lumen projector (BenQ SH910) at 140" diagonal comes in at 56 fL, a litle less then the W710ST at 80", should still be sufficient for what that video shows. At 2000 you're down to 31 fL, doable in a completely dark room if you lower the brightness of the tv.
For comparison the SMPTE recommendation for movie theatre screens is 16 fL. I'm not sure how much worse light shows on the average wall, but I guess double that should be a good start for a completely dark room.
Anyway for all we know they could have used an BenQ SH-960 5500 Lumen projector or a laser projector to make that video look good.
A fun proof of concept video, but too expensive for the average living room setup.
Shelf it for when laser projectors come down in price, that removes the problem with focus and difficult setup as well.

Now that is short throw :)

Too short if you ask me. I mount all my projectors on the ceiling and this LG would have to be way too close for a 80-90 inch picture. I bet the picture is beutiful and for a 120+ inch picture, that LG would be hard to beat. Love the no bulb to change aspect too...
To be honest, I am perfectly fine if this technology becomes an enthusiast kind of thing. The harder to set up the better... I need cool things like this to make my friends jelous when the come over. :) However Microsoft is the wrong company for that type of niche product as they only release products with mass market potential. I guess we will see how this one plays out...
