Forbes has an essay by David Gelernter:
The next Web–the Worldbeam, we call it–will resemble today’s Web imploded or, if you prefer, turned inside out. It will be a single global “information beam.” Every Web page ever posted is in this beam. Whenever someone updates a page or designs a new one, it is added to the end. The Worldbeam is a stream of many separate documents–or a beam with many documents dissolved in it, held in suspension. Both metaphors are useful.
The Worldbeam is a constantly growing journal or time line of electronic documents. Its storage is dispersed over many machines for reliability and safety, but to users the Beam looks like one structure. Like so much contemporary software, it is created by two programs working together, one on a server (or many servers) and another on your own machine; these programs allow your machine to be an “empty” computer most of the time. Information is downloaded automatically and fast when you need it, and erased when you don’t.
