Does Poser run on Linux? ;) Beowolf appears to be a Linux-only clusterer. If it's supported under FreeBSD, you might get it to work on a Mac (OSX), but then you'll need all Mac computers with OSX. That'd be expensive as well, if it even worked. In the long run, if you are determined to do this yourself, an alternative would be to have Poser on a bunch of networked Mac/Windows machines (although this isn't exactly legal). Then you copy the PZ3 file to all of the machines and set each one to render a "block" of frames as images. Gather the image frames all back to the master machine and create the animation from there. That's the least expensive solution that I can think of if you already have several machines. BYS
