Joe Justice has announced his new render controller is available for public beta.

LightNet: Cloud takes a totally different approach to rendering. It uses a FTP server to store scene data and output frames. Render nodes can be on the onsite network or offsite connecting via the internet. The settings are simple and there is a diagnostics tool to help setup. Scenes are sent to the sever via a Watch Folder. All you have to do is drop a scene in the folder and everything happens automagically.
