What will everyday holography mean?

Inspire links to an Technology Review story that PC-driven and practical holographic video is closer to reality. Among the potential applications cited are better medical and architectural modeling. Yuri van Geest asks to what extent 3-D will replace 2-Dvisualization.

MSNBC's Practical Futurist has suggested that such 3-D visualization might permit travelers to choose electrons over aircraft.

Like both, I'm wondering how practical 3-D technology, like the Internet and paved roads, will shape society. I'm also assuming - though I don't know - that there are significant differences between the technology that enables holographic video for computing and the kind that will teleport Ray Bradbury to Louisville in September.
