A link to review first:

In any event, Internet-2 is *not* about having a bigger pipe (best left to 
James Cameron - if size really does matter) - it is about having a smarter 
pipe.

Smartness may manifest itself as:
- on paper: QoS end to end
   - in practice - the ability to view an MPEG-1 2Mb/sec video with no 
packet loss from 6000 miles away.  Try watching any of these at 2+Mb/sec:

It doesn't matter how fat a pipe you have - it depends how loaded it may 
be.  Let me know how well you see it.  I see it is fine - each and every 
time - over a mere T3.
- on paper: going at 800Mb/sec end to end
   - in practice: how many TCP tuned systems do you know out there that can 
handle 800Mb/sec?   I'll make it easier - how many systems that can handle 
10Mb/sec TCP streams (sending) from coast to coast?  Try:
http://www.psc.edu/networking/perf_tune.html
   - in practice: ADSL users suddenly got huge performance boosts when they 
realized they needed to tune their Windows TCP stack.  I consider that a 
trickle down affect of I2 research, already.
