The technology ends a long drought in fundamental caching advances, says Jim Gettys, a coauthor of the HTTP specification that serves as the basis of Internet communication. While it's increasingly feasible for a school in a poor country to buy hundreds of gigabytes of hard-disk memory, Gettys says, those same schools--if they use today's best available software--can typically afford only enough RAM to support tens of gigabytes of cached content. With HashCache, a classroom equipped with pretty much any kind of computers, even castoff PCs, could store and cheaply access one terabyte of Web data. That's enough to store all of Wikipedia's content, for example, or all the coursework freely available from colleges such as Rice University and MT.
Even with new fiber-optic cables connecting East Africa to the Internet, thousands of students at some African universities share connections that have roughly the same speed as a home DSL line, says Ethan Zuckerman, a fellow at the Berkman Center for Internet and Society at Harvard University. "These universities are extremely bandwidth constrained," he says. "All their students want to have computers but almost never have sufficient bandwidth. This innovation makes it significantly cheaper to run a very large caching server."
Pai plans to license HashCache in a way that makes it free for nonprofits but leaves the door open to future commercialization. And that means that it could democratize Internet access in wealthy countries, too.

Cache Cow
A one-terabyte hard-disk cache could give students in a poor country much faster access to Web content. But operating such a cache can be expensive. HashCache offers a way to cut costs.
Legislation and industry concessions won't guarantee equal access to the Internet.
A grass-roots group of leading computer scientists, backed by Intel and other heavyweight industrial sponsors, is working on replacing today's Internet with a faster, more secure, and vastly smarter network: PlanetLab.
This just won an award at Princeton also
At last night's Innovation Forum at Princeton, in a form called EdgeXL, the HashCache technology was part of an award-winning presentation by Vivek Pai. For the university paper article on the competition, see http://tinyurl.com/cpuuww
Re: This just won an award at Princeton also
I see that article on the competition. What I was wondering is if commercial uses are to become available how much is going to stop porn and the porn industry from claiming has as its copyright for its client if they have no such copyright hash cache themselves of that particular has number they claim. Can nations just keep sitting back thinking that copyright owners are not violating their own cache while they present to the world porn industries objective, who has access to their cache plays with fire on share programs so how does that hash number get itself recognized as being the one and only copyright of such a film if there's no server dedicated commercially selling it that a share program has access? Isn't what I am saying is their unconstitutional act of aggression against society which don't deal in has numbering systems? What came first the chicken or the egg, hashcache answers so many perplexing questions of whom has a right to know - ARE WE YET TO KNOW THE TRUTH? I could also fear the hashcache bomb, how about you, leave it up to the Egyptians their computing safest facility is well below a mile of the surface of the earth where might they place a hashcache and who can access it "Al-Qaeda".
I got in a hurry to send my comment but you got the idea I was attempting to show how some HASH NUMBERING SYSTEM is not evident to all whom have caches of their own servers and of those businesses I chose to illustrate how a porn industry abuses a paid for Copyright by claiming to a Agency a Hash Number that they think is Copyrighted as their Product Name they sell on CD or DVD or on a VHS Tape. Is this their indecent truth unraveled revealing unconstitutional right acquisition worldwide or is it just in California where it is illegal to force someone to purchase porn if they don't even have it. I would refer to a 'HashCache Bomb' that causes the computer to crash having to reinstall all the files. Is this possible, Agents are making tons of money from sharers worldwide and most of those people they charge violated a Porn Clients Rights are going to jail for five years and when they return their computer will crash if it hasn't yet? Snitches that are lurking sharing programs seeking all the info on a sharer that just happens to have downloaded a particular film don't know that they are violating constitutional rights of individuals by hiding in behind a Agent that wants to know whom that individual is that has a Has Numbered File he seeks cause his Client paid him to sniff out anyone, and that Agent don't even own stock in the servers that sharers access nor the rights to claim anything about a particular share program. Big Beef taking place in California violates California Laws, I don't have respect for them even if they used clean unadultrated words in their Un-Published/Un-Copyright Supported Hash Numbered Films. What's That HashCache doing in a Legal Courtroom Summary if it was never Published by the so called Clients and Agents don't Publish that sort of stuff and expect that a court can grant them the Freedom we all enjoy because they are the Law Violators? Go ahead make a HashCache Numbering System complete so that schools can learn the Truth whenever the United States Justice System decides it is the appropriate time to tell everyone on God's Earth that its all been a lie so far and they are going to correct their lies, just DON'T VOTE FOR THEM ANYMORE OK! It is like me writing a program to safeguard Copyrights, everything that would become protected has to come first before introduction, anything that comes after the fact follows the same guidelines, the same issue came up during MP3 Legislation that a MP3 program does not recognize a particular Hash Password System in order to play that file which is required if online or offline and you paid for it regardless if it is not entered it cannot play - Caching Garbage Data. How do they cope with the lie, as long as you don't learn what is taking place they are happy people are going to prison instead of operating their home computer from a Public Facility or College - HashCache Those Prison Systems for Payroll for the mistake & HealthCare!
