This seems like one of those softwares that could really help you out of a rendertime bottleneck, if you don´t have resources for a commercial render farm.
RenderFarmer allows "anyone with basic computer skills to quickly install a powerful render farm (...) Simply install it on one dedicated computer, and it will bring up to 8 (*) render nodes up from bare metal via network boot. It never touches the hard drives in the render nodes, so it's simple to use spare computers and laptops for a big job and then just reboot them when you're done. They'll reboot into their previous state with no trace of the render farm software.(...) Supported render engines include Maya, Blender, BMRT (RenderMan), and many more! The "custom" job type can be used to support any render engine that has a command line rendering option that can run on Linux"
(*) 8 nodes in Lite version, 35 in Studio version. See pricing.
