Here's some info for those of you interested in some of the "techie" stuff
happening that WILL affect what we do.

Excerpted from an article
(http://pr.caltech.edu/media/Press_Releases/PR12356.html ) regarding new
high speed Internet technologies called FAST:
"Using standard packet size that is supported throughout today's networks,
the current TCP typically achieves an average throughput of 266 Mbps,
averaged over an hour, with a single TCP/IP flow between Sunnyvale near
SLAC and CERN in Geneva, over a distance of 10,037 kilometers. This
represents an efficiency of just 27 percent. The FAST TCP sustained an
average throughput of 925 Mbps and an efficiency of 95 percent, a 3.5-times
improvement, under the same experimental condition. With 10 concurrent
TCP/IP flows, FAST achieved an unprecedented speed of 8,609 Mbps, at 88
percent efficiency, that is 153,000 times that of today's modem and close
to 6,000 times that of the common standard for ADSL (Asymmetric Digital
Subscriber Line) connections."

WOW...WOW...WOW!!! That technology would allow a DVD to be downloaded
in...oh...about...5 SECONDS!!!!!!!
