I just found out that the above statement (by me, earlier today) is no 
longer true!

Licensing for the commercial version of PyQt now allows Python to be 
used to script or extend the functionality of the commercial application 
by its users.  You just need to purchase developer licenses for the 
people writing the commercial app itself, and due to Qt commercial 
licensing details you need to use the LGPL version of Qt.

See the 7th Q on http://www.riverbankcomputing.com/commercial/license-faq

I've also had confirmation of this via email from PyQt's author, Phil 

I don't know if my prediction that this means the end of PySide is true 
either, but it certainly changes the landscape considerably...
