Whether it's a "usb to bluetooth" or "enable usb host mode on the n800" either way I'd be happy. I bought a Dreamgear "Mini key" thumb keypad (intended for use with playstation 2, but it's actual usb) ... wouldn't mind being able to use it as a tiny keyboard for my n800. (I don't have the url handy, but I'm pretty sure the main site is dreamgear.com ... target has them on sale, on-line, for $20)
