Is it possible that you have to do "xhost +torch.ca.dal.ca"?

I just tried this, doing ssh -X to an Athena mit.edu host; doing xhost
+hostname on the local machine; then emacs & on the remote host's
command line.  Emacs started up okay in a new window on my home box.
(A little tedious waiting for X over ssh over dialup, so I didn't give
the connection a serious workout.)

I do have a /tmp/.X11-unix/XO file that's empty.  It's always there.
I never tried to figure out what it did or when.

Possible further help:

   man mcookie
   man xauth
   man xhost

"xauth -v list" might or might not offer some insight.
