PS: About KDE I'm really scared about the fact that Qt as been bought... we
don't know what the future deserves us... but I have to be on this situation
of "We just don't know", it is the worst feeling a team of developers that
worked on a project for YEARS could have.
The digia press release says they are maintaining the commitment to a free
software license version.

Sadly Qt4 is only licensed for LGPL, GPL 2 or GPL 3 not 'and any later
version.' Not ideal, but common enough for code that has a commercial
'owner' for proprietary licensing.
