How does this differ from Mighty? As I understand it, they both put the render engine on a remote server and have you VLC into it, essentially.<p>It's so weird to me that this is cost-effective, as I always expect cloud computation time to be expensive. I suppose that's mostly markup, and I don't need a dedicated machine -- I want lots of cycles for short bursts and then other people can use the same processors for their bursts during my idle time.
