nitpick -- if any GPL-licensed software is included in an executable,
then the _entire_ app *must* be GPL-licensed -- this is a condition
of the license of the  GPLed software 

the latest version of the GPL attempts to impose GPL licensing on stand-
alone apps that operate in an intimately connected fashion with a GPLed
app -- on the basis that it is a derived work, as you mention.  The 
'derived work' arqument is questionable, but has not been challenged
in court -- successfully or otherwise.

An owner of rights in an independantly developed piece of a GPLed app,
_can_ impose additional licensing requirements AS LONG AS those added
requirements do not conflict with the GPL terms.
