I'm pretty sure the Trolltech person was using "commercial" in 
the sense of "proprietary".  

Anyway, this all makes sense to me now.  The "Freedom #0" behind 
the GPL is that you can run the software any which way you 
like.... it's only in distribution that the GPL's requirements 
come into play.  Which is what they said.  

Of course, this doesn't change the fact that someone developing a 
Gambas app using the GPL version of Qt is obligated to release 
that app under the GPL.... to use the commercial version of Qt 
for a product, according to Trolltech's FAQ, you must develop 
that product from scratch using the commercial version.
