Come on .. the only reason why poppler exists is that Derek
was/is not willingly to provide a shared interface of xpdf.

This had lead in history to the fact that every software
project fiddeling with pdf has used its own copy xpdf source.
Sometimes with own patches and/or enhancements ... sometimes
with an outdated and therefore unsecure version of the xpdf

Now remembering on CESA-2004-007, CAN-2004-0888, CAN-2005-0064,
CAN-2005-3191,3192,3193, CVE-2006-0301 and CVE-2007-0104 ...
all of these programs including teTeX had to be fixed due
to the fact that there was no shared libxpdf. Beside this
I can not remember any updates on tug.org for teTeX or
TeXLive for any of those reports ;)

With the shared libpoppler all this maintenence nightmare
is shrinked heavily to _one_ package in the system ...
and even for the xpdf this would be a win ... at least
from the security and maintenence point of view.

Now the question: what is wrong on the wish to have only
one central interface in the system with may have potential
security risk in handling pdf files?
