states: "In addition, we have enhanced Poser’s remote rendering tool Queue Manager (for network-based render farms) to support GPU rendering and PostFX processing. In practice, this means a customer can render a large Poser animated sequence across a network of older CPU-only computers, high-end GPU-equipped computers, or a mixture of both. "

I take it this means we still don't get network rendering for single still images :(
