The .Xauthority file (or at least, the part of it that pertains to
your local server) gets regenerated whenever you log in via xdm.
Symlinking the .Xauthority files means that root will always have the
same cookies as <user>.

Try 'man xauth'.
h> And what does the .Xsession file that someone was talking about do?
It specifies X clients that should be run; when the .xsession file
(lowercase x) exits, you return to the xdm login prompt. In mine, I
set up some environment variables, load X resources, set up a
background window, and finally exec fvwm2. .xsession isn't really
relevant to this particular problem.

Subject to the other rules about who may connect to the X server
(xhost/xauth access control), yes. xauth really is a better way to do
this than xhost; see the xauth man page for an example.
