Is there any wiggle room for the pdf requirement as the document
source? The reason I ask is that pdf is not a particularly good choice
for the raw document source given the other requirements. It makes a
great export / publishing format, surely, but ideally the document
source itself could, or should, be in a more editing friendly format
(eg html or ms-doc). Then when its time to publish, just hit a button.
That would give many more options for the other requirements.

That being said, if they can start with a more neutral format, google
docs has some great collaborative tools, including revision history,
notations, and real time per document chat (a new feature). And can be
published or shared at any point, of course, as pdf.

Another option is Adobe has an online document collaboration suite,
that is "free", and surely supports pdf. Not sure about all the other
requirements but might be worth looking at.
