I'd like to have offices in a ring around the globe, maybe one in every other time-zone, each with an open floor plan and two opposite walls set up as full video walls with cameras and two-way connections so that it supports the illusion of looking into the neighboring offices through windows. There would be sound if you're standing close enough, and several scanner/printers (FAX machines lol!) connected so that you could feed a hard-copy to someone on the "other side" of the "window".

It would be so cool to look "across" the distributed meta-office and SEE the day/night cycle all at once though the real windows in the offices.
