I know that lots of mac users want an external graphics card. The Asus thing is never gonna come but there is a product called ViDock (http://www.villagetronic.com/vidock2/index.html) that has mac compatibility. It is an external graphics card dock that connects to a pci port, and can except any card that will fit. The company says it is only compatible with the 2.3GHz 15inch MacBookPro, but the only reason is it's pci plug in. There is another company that makes a similar product that connects via vga plug/pci adapter, but it is several thousand dollars. I would like to blindly assume that the later product could be connected to a usb to vga adapter, but is there such a thing as a usb to pci adapter? If i could rig something up would this even work? My optimistic setup is; ViDock-pci adapter-usb-bingo.
