You're welcome to distribute pdf2swf from your site. Just make sure
you always also offer the source code (the .tar.gz) archive together
with the .exe files (In order for the GPL to be fullfilled).

One question, though: How do you link pdf2swf together with your
application? Via command-line, or by re-compiling/linking the C++

http://www.quiss.org/swftools. That's sufficient, as far as I'm

In principle, you can also offer them for a fee, if you follow a few
(GPL induced) rules:
1.) Every software you send out (via mail, download, CD/DVD etc.) must
    always be accompanied with the source code of swftools (the .tar.gz
    archives) If you distribute a modified/enhanced version of pdf2swf, include
    the full source code of all modifications/enhancements, too.
2.) You may charge for the "act of distribution", but not for the
    software itself. In particular, you must not offer the software
    under any different license than the GPL.
