I have downloaded
 http://partners.adobe.com/public/developer/en/xml/formcalc_2.0.pdf
If I have understand it FormCalc seem to be a simple script language
Seem that Acrobat 7.0 can do this, but I'm not sure;
asap I try to make an example.
i played with xfa stuff some time ago; it boils down to sending an xml file to acrobat with a ref to a pdf file and additional form data; so maybe the form calc code stays outside the pdf file in a parallel file
I have put a simple example under
http://www.logosrl.it/context/test/tex.pdf
It was done with Designer; it is
var Quantity=100
(I wasn't able to make uncompress vers. for pdf 1.6, so I downgraded to 1.5)
It seem that xml data are embedded into pdf.
as far as i can see it boils down to embedding a bunch of xml snippets (none of which is valid xml in itself) and add an /XFA entry to the Acroform dictionary in the Catalog; no big deal; the plugin reassembles the embedded files to something valid xml and then does something with it, probably depending on the javascript; 

(looks like a real mess of mixing javascript and another language; i wonder why they didn't use javascript for everything; maybe the xml hype stroke 'm) 

So, here's something rather preliminary to play with ... (use / in filenames)
