Using a "Tragedy of the Commons" analysis on telecommunications systems 
isn't very appropriate.  Modern telephone systems have a fairly well-defined 
instantaneous capacity, do not wear out based on usage, unused capacity 
doesn't 'store up' for later use, nor do sporadic attempts at excessive use 
have anything more than a very transitory effect.  (fast busy signals.)  And 
in addition, a person doesn't profit in an unlimited fashion by attempting 
to over-use the telephone:  Nobody I know would spend 24 hours per day on 
the phone if it were free, for example.  So there's little motivation to 
over-use the resource.

The Internet is even more "friendly" along these lines than telephone 
systems:  The Internet doesn't "fail hard," denying access when usage is 
high, it merely slows all access to match the need.  There are enough 
differences that I think Internet deserves an entirely new analysis.  Don't 
worry, it will be also be interesting, from a game-theory perspective, but 
it will be very distinct from a classic "tragedy of the commons" situation.  

The current question is how to motivate individuals and companies to invest 
in improvements to the Internet that will benefit everyone. However, I don't 
think that will be the limiting factor that it may currently appear to be.  
Due to the nature of the Internet, there is nothing to prevent a company 
(such as AOL, Compuserve, or other) from building a shadow version of the 
Internet, through which all of its customer's traffic will pass until it 
emerges local to its destination.  Customers who appreciate this kind of 
prompter service will be motivated to pay slightly more and will buy 
Internet access through that company.  So the "commons" won't be quite so 
"common," and product differentiation will allow choice.
