Does anyone have any idea how to do this? Even something close might
help.

In the absence of any response from someone with more definite
information, I believe there is a 3rd party iFilter for pdf  files
that you can buy. One of its advantages over the Adobe filter is
that it can extract metadata  as properties  that you can extract for
search.

I guess though you would still need to write custom code to promote
these properties into document library  columns.

I'll reseach that more. I was under the
impression that the iFilters were primarily for Search and indexing.
I'll keep you posted on what I find out.

iFilters are used for indexing because they understand the underlying
structure of a binary document  and how to retrieve metadata  from within
that structure, something the indexor needs.

I'm finding that there is a very limited
amount of information  about how to promote  PDF properties  up to a
document library's metadata  columns. Even the PDFs I create/publish
in Word 2007 don't propagate the properties to the doc  library.
There has got to be a way to do this.

I've never read of anyone successfully doing it. It doesn't behoove
Microsoft to promote  the PDF standard.

Here's a code sample for a 2003 web  part that claimed it would autocreate
site columns based on EXIF metadata  from JPEG images, so it's conceivable to
do the same with pdf  metadata.

Another thought is that with pdf metadata iFilters if you just need to
display the metadata for library  of PDF documents could you make a web part
page that connects a list view of the doc  library and a search result part?
So when you click on the doc title in the list view part it passes that
information to the search result part to display the metadata as a custom
search result on the same page?

I have my developer buddy looking into the custom web  part route. It
probably will not do what we're looking for, but there may be a way
using an offshoot to your suggestion.

As far as Microsoft's support for pdf's, I understand the reasoning
for them not to come out and endorse the standard. That is their
way. However, the partner ecosystem is missing out on a large
opportunity with MOSS2007 exploding in popularity for enterprise
content management. I guarantee you that there are plenty of
organizations that are storing pdfs  in their doc  libraries and would
like to see the properties  they've defined for them automatically
exposed.
