I can't see this working - I went through the same problem with the
tiOPF project.

If you create a CGI application that pulls in the Forms unit for
example. Then try and run that CGI project thourgh a web server that
doesn't have X Window System installed, the program will fail with
"DISPLAY has not been set" error.

In the case of tiOPF. I was trying to run the console Test Suite on a
headless Linux box. I had to first clean up the tiOPF code, to NOT
include GUI units in the core tiopf unit. Then only did my console
application run correctly on the headless linux box.
