OK folks, I think we are way past the end of the useful part of this discussion, and it's time to come to a conclusion. I'll ask people who want to continue arguing the fine points of the LGPL to please do it by private mail.
My conclusion is that there clearly isn't enough support in the developers community to justify changing the license. So I'm not going to proceed with any change, either now or in the foreseeable future.
Thanks to everybody who participated to the discussion, and now let's go back to writing code...
