I agree that general support for PyQt4 is outside the interests and 
goals of the developers, but it's not necessarily outside the interests 
and goals of other Vpython users.  (As far as sample programs are 
concerned,  I can argue both ways.  There's room for discussion.) Qt has 
some nice features.  I have been planning to look at Vpython PyQt 
integration after the semester ends.

I don't think that the licenses vary by platform in PyQt4,  but they did 
in PyQt3   (I may be wrong about that.)
There is a GPL version of PyQt4 as well as an educational version and a 
commercial version.   I can't read legalese, but IFAICT all three 
versions are identical except that the commercial version allows for 
inclusion in commercial products and includes support,  while the 
educational version includes support. 

Without a doubt, the website is not clear on this, and installation 
instructions are not the best (and possibly even wrong).  Without a 
doubt PyQt4/Vpython is not for the average user.

In the meantime, I think this list might be the right place to discuss 
the technical issues.  As I said, I want to explore the issue, but not 
right now.
