Well, yeah we can dicate the Adobe Reader required.

Any ideas where? Which classes? Sorry, I am 2 weeks into using iText
and a tad overwhelmed ;-)
TIA

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?

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...
