I just emailed to Apple to see what their official word on this is.
You don't think that any clarification should have been left to Kitty to get on behalf of all concerned parties? I'm sure it would have been very much in his interest to get us a swift and definitive answer.
Btw, chaps, if you're interpreting Apple's T&C's to the letter, then every one of you discussing this in a public forum will surely lose your Apple Developers License and it'll no longer be a concern for you anyway? No, I don't really think this will happen. And I don't think Apple will block GLB, Unity, Torque, GameSalad et al in one fell swoop. But I also don't think you should specifically poke the bear.
