. I have a keyboard that does macro's (comfortkeyboard) and it's convenient to remember long passwords; but it doesn't have an SD card for backup; and, that brand of keyboard is too expensive . . to replace it, some adapter device (or fully software solution and a cable hack?) should connect a laptop's {ethernet, usb} to another computer's usb, in order to have more control over "keyboard" output; the laptop holds your passwords and macros; you can also send output in batch, as with instant messaging: I can check what I typed, then hit send; I can also record everthing I send . it should pass as a generic keyboard such as useful for booting into mac os x .
