Amazon is offering, for real cheap, their web services engine. I'm not an IT guy, so I don't know the jargon. Jeff Bazos explains the idea.

In short, Amazon.com has launched several services that allow small companies to leverage the powerful tools of a big company such as Amazon.com. For instance, Amazon Elastic Compute Cloud (EC2), creates a virtual Web-based Linux server that a small company can rent at 10 cents per CPU hour. That means that, if I’m a tiny start-up business that wants to process a lot of data, but can’t afford to invest in an expensive battery of servers, then I can simply use Amazon’s for as long as I need the processing power. Let’s say you are a small research firm that has just finished a survey and collected a lot of data. And you have a one-time need to crunch a lot of numbers. You could rent one virtual server for ten days, or, conversely, you could rent the equivalent of hundreds of virtual servers for one hour and get the same task done. Since it occurs elsewhere, it is almost infinitely and instantly scalable.

Seems like a good idea to utilize CPU capacity. Now if we can just utilize unused brain capacity...
