Running glxgears on the PS3 using ssh to my Powerbook resulted in a claim of ~1500 fps and much faster apparent speed (even over my slow LAN - ~1 Mb/s). Of course, the Powerbook does have acceleration for OpenGL which makes up for the slow network (so the rendering is done on the Mac's server). I still don't believe the reported numbers.
