Just to clear up the point Khalid *might* have had in mind:

Does the Free QT license cover you *even if you're developing a
commercial retail appliance-style product*, as long as you comply with
the letter of the GPL?

(IE: WRT54G...)

Specifically, some GPL'd code won't conveniently run on anything but
the commercial hardware it was released on, because it depends on
special components or the like -- an example of this is the fixed
PoPToP that Moreton Bay shipped on SnapGear router for some years --
they had fixed things that broke multi-session handling, but their
patches only applied atop other patches that made Linux run on the
Coldfire processor, and the net outcome was that PoPToP stayed broken
for some years more.  (I think it's finally stable now, but this burned
me with a client for a couple grand.)
