It will be very interesting to see their response because I don't think
their license anticipated things like PyQt and PerlQt.  Their income is
from developers of commercial packages using Qt - you couldn't develop a
commercial Qt program without giving them money. Because you are allowed
to distribute the libraries with your program at no additional cost you
are effectively buying a copy of the header files.

With PyQt you don't need the header files. Only one Qt license needs to
be bought (or gets donated) for everybody on the planet to be able to
develop commercial Qt programs (in Python) without Troll getting a

On the one hand PyQt could be competition for Troll, on the other hand
it could be a way of getting Qt to a wider audience.

By the way, if anybody wants to donate a Windows C++ development
environment I could properly maintain the port myself.
