[Qt-interest] Licensing

[peter]

Hello Kusti,
I'm a "commercial" user, I bought QT 4 and have a support contract with 
the trolls. This allows me, to deploy my applications with qt 4 without 
source code and without the restriction to deploy things, I changed in 
the QT sources, in source code. So I'm free to modify everything without 
the need to ship sources....

Nokia wrote, the LGPL allows to write commercial programs without the 
need to ship sources, as long as the orginal QT sources are untouched. 
So I can write commercial programs and can deploy the original LGPL DLLs 
(I am a windows programmer)

Only programs, developed with LGPL or GPL QT are not allowed to use 
later in a commercial environment....

In my opinion, commercial to LGPL or GPL must be possible, because I 
bought the commercial license once and it belongs to me a lifetime.

But my native language is different from that license document, and my 
"english" is not perfect, so some things could be misunderstable....

Best would be, to have that license documents in the native language....

Regards,
peter
