"You must purchase a Qt Commercial License from Qt Software or from one
of its authorized resellers before you start developing commercial
software. The Commercial license does not allow the incorporation of
code developed with the Open Source Edition of Qt into a commercial
product."

In effect this means that if you want to develop any commercial software
with Qt you have to buy the license in advance (even if all you want is
to knock together some proof-of-concept) and you are also
permanently locked out from including any previously developed Qt code
which the wider community may have produced.

With other GPL licensed software you have the option of approaching
the original author and negotiating with them for their code to be
relicensed for use within your proprietary product (or the author 
could simply distribute their code under a less restrictive
license to begin with), but the Qt license restricts you from using
anything publicly available *except for Qt itself*.

It is a novel interpretation of the GPL. Qt Software have every right to
impose this sort of condition, but it makes me want to avoid them.
