From the Freehacker article I surmise that it's Plura Processing (http://www.pluraprocessing.com/)

"[...] in fact was announced on the Digsby blog as an official way they are going to make some money, with Plura Processing as a partner."

As to whether or not you can supply processing power for a fee, I doubt it. Looking through their individuals page briefly it looks like it's very similar to SETI@home or any other distributed computing effort. If you like the projects they're running you help, if not you don't.
