Good Start. :-)

Ah... When /I/ run ssh -X user at home.hostname, it automatically sets my DISPLAY
variable for me.  Not only that, but ssh forwarded X usually is a helluva lot
higher than :0.0, for example, in my case it's :10.0.

This is a setting in sshd.conf, and is a constant that is added to the ssh
connection number (counting only ones that are doing X forwarding).  So if you
connected to the box with X forwarding, then I did, my display would be set to
home.hostname:11.0  -- NOTE that this is the machine name I'm sshing into, not
the machine name that I'm connecting from.

Probably it wants to be something like DISPLAY=sunbox:10.0
