The non-commercial v2 combatible version of PyQt will be restored with the 
next release of PyQt (sometime next week).

The educational combination of PyQt/Qt is available and works fine.

At Trolltech's request there will not be a version of PyQt released for the 
non-commercial release of Qt 3.2.1 (the "book" version).

As of the next release there will be an evaluation version of PyQt that works 
with the evaluation version of Qt.
