Restrictions or taxes on the use of modems, for

 The Challenges and Promises
 No electronic network mesh has consistently grown
on the scale at the speed of the Internet. As a result, it
has throughout its history been constantly challenged
to develop new technologies, standards, and
administrative techniques to provide greater band-
width and additional services to more users through
ever more complex architectures. However, each
order of magnitude scaling becomes more difficult.
 Problems associated with addressing and security
seem largely transitory - with a combination of tech-
nology, new statndards, and administration provid-
ing effective solutions.
