And bandwidth still changes everything. The thing that made browsers
fun was that the latency was tolerable, and that was only true because
the network performance was good enough that imagery was feasible to
move over the net. It's no surprise that new technologies such as the
WWW and browsers came from places that had interaction with the Gigabit
Testbed program, such as NCSA and CERN.

Way back when I was planning what became the Gigabit Testbed program,
many people I talked with said "who would ever need gigabit paths
between organizations let alone desks. " But there were those like
Erich Bloch at the NSF and others including Bob Kahn and Jon Smith,
who saw the future and supported the idea. That initiative bought
gigabit capacity to the national internet a good 3-4 years before it
might have happened otherwise.
During the planning I went over to my colleagues at Wharton and asked
what their community could do with gigabit capacities. After 15
minutes I had to stop them and say that we were not yet capable of
supplying the bandwidth they wanted. They were visualizing real
business application that if successful could save enough money and
give enough flexibility that the cost would be irrelevant.
What they need is 100 gig or more channels and systems that can
generate and absorb data at those rates. Saddly I don't see the same
commitment to doing the research that will yield that environment as
eventually we saw in the Gigabit testbeds.
