Mass storage, for example, is worth more if less expensive, faster processors can execute more demanding compression algorithms. Memory is worth more if high-bandwidth processors can sharpen and color-correct a video stream, to mention just one application, as easily as they used to optimize a single image frame. But the real explosion of processor demand doesnt come from high-end applications for chips that cost hundreds of dollars. It comes from the hordes of simple applications, formerly less expensive to do with hard-wired logic, migrating to software on newly affordable low-end general-purpose chips.
If only all those general-purpose processors could find jobs to do in their spare time. Suns Project Jxta, a hot topic at this years JavaOne conference, proposes a framework for spontaneous collaboration among processing nodesand a peer-to-peer framework like Jxta doesnt merely partition existing large tasks. It also enables exploitation of previously invisible opportunities: for example, as suggested during Bill Joys JavaOne demo, to have all the cars near a given gas station negotiate as a group for a discounted price.
