Networks are by definition designed for one computer to talk with many
other computers. Under the ideal situation the computers would talk to
each other at the same speed it talks to its self (bus bandwidth, memory
speed) creating a single virtual computer.  Due to the engineering
constraints of doing this, using the bandwidth that is available,
applications have been written that are "network specific" eg. slow.  This
constraint will always drive bandwidth to higher speeds. Thus it follows
Moore's Law as chips get faster, so will computers and conversly -
bandwidth. There is no end in sight for the need of more bandwidth.
