Last week's decision by the U.S. Supreme Court regarding file 
sharing will  likely put a serious dent in the market for 
peer-to-peer systems that permit  users to share files, such as 
music and video.
The Supreme Court  ruled that providers of peer-to-peer software 
can be held liable for files  that are illegally copied using 
their tools if it can be proved that they  encouraged users of 
their tools to violate copyright law. Because copyright  
violations are punishable by huge fines for each offense, the 
ruling  could easily make peer-to-peer companies liable for 
hundreds of millions of  dollars in damages in future lawsuits. 
One source estimates that more than  30 billion files are 
illegally copied every year.
So what does this  mean for the typical enterprise? It's 
important to understand the impact of  peer-to-peer on your own 
network. There are several tools available that  will allow you 
to scan your network for peer-to-peer traffic and get a basic  
understanding of how much peer-to-peer traffic your users are 
sending  and receiving each day.
With that information in hand, it's important for  any 
organization to formulate a policy about the use of peer-to-peer  
systems on the computers it owns. Just like having an 
acceptable-use  policy about e-mail and instant messaging 
systems, it's important to have a  similar policy about 
peer-to-peer use. This is made all the more important  because of 
the fact that an organization that allows peer-to-peer users to  
share content using its computers in violation of copyright law 
could  also be on the hook for damages if an employee is caught 
violating the  law.
As an example of a good policy is the one that the Anchorage  
School District has established, which reads, in part, "Illegal 
copies  of copyrighted material may not be made or used on 
District equipment. The  legal or insurance protection of the 
District will not be extended to  employees who violate copyright 
laws."
Any organization must  understand how much peer-to-peer traffic 
is traveling across its network and  the nature of this traffic, 
and it must formulate a clear and concise  acceptable-use policy 
for peer-to-peer systems. Not to do so exposes an  organization 
to enormous liability.
such a joke....people will simply burn CD's and mail them via snail mail.
