But that's a little bit like standing in front of a mountain and saying "Go
away", isn't it ?

On the other side, from the viewpoint of the ZPL, these requirements of the
GPL are the limiting factor.

But I'm afraid the discussion on who's guilty won't solve the problem, which
indeed is perceived by all of us (is it ?).
