Ok, so i guess you are saying you are not going to dig the code and create the 
library yourselves, right?

I would say we (poppler devels) don't have enough the time for that either, so 
i think we should try to find a "new developer", and you would guide him 
through the pdfTex internals and I will answer the questions he has on 
poppler. Agree?

That way we all win (in case we can find the person :-D)

poppler does not depend on X11 nor gtk.
