Depends on the projector. Cheapest 3000 lumen I can find is Vivitek D860 svga (800x600) DLP

At 120" it should work in a dark room with the tv brightness turned down, at 100" it will work with normal tv brightness and ambient light.
You'll need a more expensive short throw projector though as this one already needs to be 12 ft away for 100" diagonal.
I guess it is possible to make a $300 mass produced short throw svga 3000 lumen projector. With a 100" diagonal it would still give a decent effect. (Although more IllumiBorder then room)
It won't be a mass hit though with a $300 price tag. It doesn't have the same marketability as Kinect, more comparable to a niche product like the Playstation 3D display.
