> Why? Construction management is, at its heart an exercise in coordination. Performing that coordination efficiently requires looking at the big picture, and literally looking at a big picture 8 square feet at a time cannot be replicated on a screen.

Perhaps a tablet + projector would. Last night, I was at a friend's kid's birthday party, and they took a nice big wall, a projector,appletv and airplay mirroring the content of the iPad to watch movies and play games. The most interesting part was where the host was showing something to the kids, and the kids would take turns to correct him (and show him how they would do the task) as they passed the iPad around. It was absolutely sublime to watch.

Currently it's a tad clunky for setup (requires 3 devices) but if you merge the three devices into two (or even one) it could be relatively tasty... add in webex-style teleconferencing for flavor.

Just running the numbers and assuming 100dpi output for convenience, that's a 12 megapixel projector, before one addresses finding a suitable projection screen on the jobsite and ruggedize the electronics.
