True, you do get more done splitting the frames up across machines, but being able to render single test frames with multiple machines allows for higher quality GI renders and/or quicker renders. A reason I've stayed away from alot of GI is the testing phases are killers for time! Eric - Have you done any animation renders to see if what GWeb says would be quicker? Or would the 'render-farm' approach built-in be quicker? Or, to push the envelope further, if one was to have multiple installs of the master, and sets of 5 computers hooked to each, would you be able to split frames across multiple masters, and then have 5 slaves each to speed up high-quality sequenced frame animations? (Of course, one would also need multiple liscenses of C4... but you get my drift...)
