This works fine when you're doing stills with simple scenes. When you've got GBs/TBs of external assets in the form of source geometry and texture data, all nodes need access to the same source data. Once you start doing Monte Carlo path tracing and need decent sampling, you've also got to be careful that each node is generating the seeds for the random number generator correctly, otherwise you get patterns in the noise when you piece them back together. For animated stuff, you're better off distributing the different frames across the nodes instead of splitting up each frame.
