A few questions:

1) What are the difference between qt-x11 and qt-x11-free.

2) Why is it called qt-x11 and not just 'qt'?
   I guess this is because you can build qt-embedded (Is that for 
   framebuffer)? or perhaps there even is a qt-fb for that. Anyway, my 
   point is, why not calling "regular" (x11) qt just plain and simple 
   'qt' and use an extra ending for the others?

When/if EClasses gets accepted they won't be restricted to KDE-use
(right?) and should probably be used for all qt-apps (and probably
others), meaning that if it's an qt2 app it inherits qt2.eclass and if
it's an qt3 app it inherits qt3.eclass.
