the idea is  actually not as far off as one might think.

due to the success of folding@home and the ps3 sony is looking into delivering the same type of solution to commercial applications and companies.

Now, granted e.on´s a small company so i bet it wont be the first one sony has in mind, but with the right tools and support of course our ps3´s will sooner or later find it´s way into design and media related stuff for it´s distributed computing powers, and a renderfarm for sure makes sense, pity tho i recon we´ll have to be patient like .ell to see it happening with vue.
