Export the actual ip address instead of "oafish" or "my_home" before you
run xemacs (from the remote machine). If you use bash (assuming ip
1.2.3.4):
export DISPLAY=1.2.3.4:0.0

If you run a variety of csh or tcsh:
setenv DISPLAY 1.2.3.4:0.0

The problem is that it doesn't know how to resolve a named address to a
machine with dynamic ip.
