exrTrader is ScreamerNet compatible and allows for network renders. You can install the plugin on any render node and it will render as expected. It has been tested with a variety of third party render controllers, including Butterfly NetRender and Spider.
The OpenEXR Dummy Saver has been designed to allow render controllers to check for saved frames from rendered scenes, even if only the exrTrader Layered Export is actually writing frames.
