To work remotely you use the FQDN appended with the DISPLAY number (as opposed
to localhost/unix:0) to get the TCP connection cookie.
user_one# xauth -n list host.example.com:0
10.0.0.1 MIT-MAGIC-COOKIE-1 92b21b394ac0c5afe1fee0a973b9e49g
This will only work if Xorg is listening for non-local TCP connections though,
which is NOT the default.
I almost always use XForward'ing over ssh.
