If you bridge the AirCard connection with your Ethernet on the desktop I think it would work. The aircard is a cell modem not a wireless card so yeah the Xbox isn't going to connect to it. You could try it on the laptop. I'd try it with Vista only cause I'm not sure how to do it under Ubuntu( isn't it a great OS tho? I dual boot XP and Ub )
Just make the connection with the aircard, then go into the connections and bridge it with your ethernet. Connect the router to it, not sure if it would be the WAN/Internet port or just one of the four. Try both. lol You can always un-bridge the connection so it'll go back to normal. I'd not complicate the router with any security tho.
I am just guessing at this tho lol. Let me know how the experiment goes.
Hope this helps
