The only "problem" that I've found to do all the process is that Dia
needs a X session to work, and I was wondering if it possible to use
the command line export option without this need (I am not a
programmer, so if I'm saying stupid things, excuse me). If it's
possible to do the export process without any gtk-display, I think
that Dia can be easily use to these kind of interactive diagrams.

There are fake X servers available, but running Dia without GTK would be
difficult at best.  For one thing, text widths are calculated by GDK
(though that can be done with FreeType now, but it asks X for font
information, too).  Hmmm... looks like I broke PNG export in CVS by
adding a dialog.  Gotta have a check for noninteractiveness.


Once FreeType will ask the X Font Server only, there will be more
chances. I don't know why it doesn't do it yet...gotta ask now. With dia,
you must have your font path defined in XF86Config, but for mozilla (as
an example), that's not needed to actually get your fonts working.

Some programs use various hacks to get fonts paths, such as hardcoding
typical font paths or looking for them during installation.  I'd rather not
have to resort to such.  

I'm thinking there are other difficulties in making a non-X version of
Dia.  Can't point at specifics right now, though.  The startup does some X
stuff per default, and it's uncertain how much GDK stuff depends on
gdk_init having been called.  If you want a non-X version in order to
reduce startup time, start by looking into not loading any sheets or
plugins you don't need.
