Speaking of xauth and paranoid X security, does anyone know how to get a client to display in an Xnest server? The default security seems to be so high, there there isn't even a way to run xhost to turn it off because xhost isn't allowed to communicate with the Xnest server :-). The only way I've ever gotten anything to work in recent versions of Xnest is by using the -ac option to totally disable all security.
