I had a "business plan" doing this once. Letting people connect their browsers to some page and get paid for it, with other people paying for the cycles. I figured the demand wasn't there, and that you'd have to make it so servers could participate without a browser / remove the reliance on JS to make it viable. If you could somehow let gamers offset the price of their GPUs by putting GPU-cycles up for sale through the browser one might have something though.

Ah, yes. Distributed DES bruteforcing with a Flash applet - those who haven't thought of it at some point in the past, raise your hand.
