The entries in .Xauthority are generally of the form
hostname/protocol:display, so as long as all of your hosts aren't
named "localhost" (they all have different hostnames), it should Just
Work.  A workaround which you could use (in case there's some reason
you don't want to do this properly) might be to make $HOME/.Xauthority
a symlink to something like /tmp/$LOGNAME.Xauthority.
