Nope. As stated by someone here (Oleh, I guess), if I (require 'org), or possibly even just write Elisp, and want to distribute it, it has to be GPL. > If your code is not based on mine (or any other code released under > GPL), then by all means do what you want with it and give whatever > rights away you wish.

It boils down to the question "how much of other code (even rather generic parts) can I take and still consider this *my* code)".

I'm glad to hear that we (more or less) agree.
