Will you get out your personal checkbook and write me a check for a brand-new $100,000 numerically-controlled milling machine based purely on a voice you've heard down the phone line and some grainy webcam images?

I think not. People have a fundamental need to "see it in the flesh," and that will never change. As oil becomes more scarce, the bar will simply go up on business travel, and all air travel will once again revert to an elite, unusual activity, rather than the common activity it is today.

I don't know--I mean, academia is my only model, but people regularly receive grants for multiple hundreds-of-thousands-of-dollars based on the recommendation of a panel of judges (and no face-to-face interview).
