An idea for an alternate adapter-gadget-thing: I've heard random rumors of battery-powered USB hubs before. Seems like a nice N800 accessory would be a 'backpack'; a custom case to clip under the kickstand of an N800, with a mini-usb cable and power cable coming out one end (to connect the N800), and inside a bank of, say, 3 9V batteries, the powered hub, and a charging adapter. Hours of runtime, 4 powered USB ports, and a handy brick-like form-factor (which probably would bother some people a lot more than it would bother me.) I don't expect you're interesting in fabbing up some backpacks, jolouis, hence putting it back here rather than the new adapter thread.
