Actually, using -nolisten is okay as long as you aren't cross-connecting X
servers and X apps between machines.  It's generally considered a better
practice to use unix domain sockets than TCP when your X server(s) and
application(s) are on the same machine.

Besides, if your home directory is mounted via NFS, your .Xauthority file
is accessible to anyone with root access to the network.  In a sense, it's
(not "its") effectively chmod'd a+rw.  So, in this particular scenario, you
would probably WANT to use -nolisten.
