RE: Setting DISPLAY across telnet/rlogin

Both telnet and rlogin preserve the TERM variable (at least in my experience -
maybe it fails in some locations). You can use this fact to pass additional
information along by setting TERM to be something like "real_term@display",
and then having the .login / .profile pick look at TERM, and if it's of this
form, extract the information, set DISPLAY, and fix TERM to be just
"real_term" again. rlogin and telnet can then be aliased/functioned to set
TERM appropriately just before executing the real binary. I have code here
that works under ksh to do this, and it seems to function quite nicely. I
can give you a copy if you'd like.
