Well, it seems like all the authors agree and there's already an LGPL license. I only brought up all of this due to the inconsistency between whats actually there in the source files. I'd love for that to just be changed and we all move on. It's not like this is a huge patent / money maker thing. If being anal and bringing this to light truly means I *can't* use it in the long run, well than I should have done what most everyone else does in these situations: use it and keep my mouth shut :P.

We know what is allowed / not allowed by Apple, don't need a lawyer for that.
