Have you tought about creating some sort of rendering nodes market? I mean, many people have powerful hardware that can be used for rendering by other people, but they don't want to share their computers with strangers for free. It would be great to be able to rent out computers in public cloud, where other people could get them for rendering using your system. For 3D artists it would be great too, because it should lower costs and make cloud much bigger and more accessible for all.
