Indeed. You could also use the PS3's VRAM as swap space when using OtherOS (Linux) before Sony removed OtherOS. GPU malware is going to become really interesting once memory-coherent GPUs (like PS4's APU) become more available. That combined with something like packet mmap [1] may allow for data exfiltration from a GPU compute kernel without ongoing userspace assistance (MMIO packet send/recv => no need to have the CPU userspace side dispatch syscalls on behalf of the GPU).
