This sounds like something that should be implemented using GNOME's
accessibility (a11y) framework.

Are you working with pygtk? If so, I think the slides from James
Henstridge's
talk "Remote Control and Scripting of Gnome Applications with Python", given
at
Linux.conf.au 2004 would be interesting for you:

Maybe gok (GNOME On-screen Keyboard, http://www.gok.ca/) is interesting to
you
as well.

Well, I'd be much happier to accept patches that fix a11y bugs in gpdf
than patches that add new CORBA interfaces or Bonobo Verbs.
