When it comes to "lawyering up" How would one even go about suing someone
who distributed a module that was designed to output XML specifically for a
non-GPL'ed Flash image gallery test the "single system" definition?

Adding a disclaimer to modules is only going to make problematic situation

If you take even a quick look at the Lulabot's "top 40" modules, you'll find
third party code in several of them (it's easy to spot because most
developers are nice enough to leave the code's credits in the module)...

40. XML SiteMap - http://drupal.org/project/gsitemap
- includes gss.xml (12K) found at http://sourceforge.net/projects/gstoolbox

39. Location - http://drupal.org/project/location
- includes earth.inc (6K) by Ka-Ping Yee

36. Porter Stemmer - http://drupal.org/project/porterstemmer
- includes the PHP implementation of Porter Stemmer by Richard Heyes
available at http://www.tartarus.org/martin/PorterStemmer/php.txt

16. Audio - http://drupal.org/project/audio
- includes XSPF Flash player (139K) found at

There is also Jeff Robinson's JQuery Update that still includes versions of
jquery.js 1.1.2 and compat.1.0.js.
Drupal's CVS maintainers don't just discourage third party code that isn't
GPL compliant, they expressly forbid it regardless of license, reasons given
for including it, or how nicely you ask.  If including third party code was
only a licensing issue, TinyMCE would be much easy to install and
