that shouldn't be an issue, as apple does not use kdecore anyway, no?
how could they use kdelibs without a qt license otherwise, anyway?

yes, the viral character.

if you use qt under gpl, kdelibs is already "infected" anyway, so it
would not matter.

why? under these conditions no gpl code would be included in the first

for my idea to work out, two conditions must be met:
- anybody being allowed to distribute the code in question without
  actually granting a license to use it (other than gpl, that is). that
  should be covered by the qpl/gpl+exception, no?
- buying a qt license would have to imply the right to use (older) qt
  code "extracted" and distributed separately from the purchased package.

now that's the catch.
ultimately, this needs to be cleared up with tt legal, i guess.

Hi! I'm a .signature virus! Copy me into your ~/.signature, please!
Chaos, panic, and disorder - my work here is done.
