I guess the question, fundamentally, is: is the Qt license
free enough that it could be used in Blender? If it is,
then I think that's fine. I certainly didn't intend to
suggest that I wanted to place any restrictions on how
Blender could be used.

My position, basically, is this:

1) I do not want companies to be able to create software
    for profit using Carve without either compensating me,
    or distributing the source code to that software.

2) Subject to 1), I want to be able to make Carve as
    widely and freely available as possible.

I'm pretty sure that that's entirely compatible with
GPL dual licensing, and reasonably sure that that
doesn't provide any sort of roadblock to Blender (as
Blender is already GPL'ed).
