I thought the LGPL covers both cases. If someone wants to write a commercial 
application he has to go to Trolltech for buying a license. And the binding 
is just additional code which is linked against Qt? What is with the kde-libs 
guys. Can they sleep peacefully?
Otherwise, the GPL would be a good choice, too.

:-( I hope it will be ok with that name.
