Well, in essence the PDF's will be agency created and may or may not

Not allowed by some rules/policy outside the programming system - yes?
If you are dealing entirely with Windows, then if you can
also assume that all users have either Acrobat 4 or later, or Reader
5 and later, then you should be fine technically.
I am basically trying to fathom if I can tell if the PDF can be
submitted online (to a CGI script or alike). Can I tell if the PDF
has a form action and/or certain property which can tell me if it
can be submitted?
Well, you can certainly tell if a PDF has an action
associated with it that is a "Submit Form" action - which is the
simple & historical way for form submission. This is well defined
and not too difficult to develop a test for (either with iText or other tools).
However, there are also more recent techniques for form
submission including JavaScript, SOAP and XFA-based forms that are
all "online" methods. This is more complex because it would mean
parsing JavaScript and XML and determing what's in there...
