The FAQ unfortunatly has a legal opinion that is probably not
compatible with most copyright laws, especially German

If a plugin is not based on code of yours but rather uses an
interface to "communicate" with it - be it fork/exec, function
calls or other methods - it is not a work dereived from yours, so
your copyright simply does not apply.

Even an include() statement does not make the plug-in in the form
it is _distributed_ in a dereived work.

Further, it might be a violation of antitrust laws if GNU software  
becomes more prominent.

It is probably not a very good idea to test this aspect of the GPL
in court.
