All ideas are already generated

After seeing flash websites take enormous amount of my CPU got a cool idea today about using flash for distributed computing. Basically everything is already in place. You setup webserver, share content with flash, it runs on client computer and does calculations uploading the result from time to time. Certainly I wasn't the first who invented that, see for example

and

Though such ideas are rather recent and the question is how to make this framework widely used. Looking at current load of the computer at sourceforge it's most likely already used by some websites :)
