    You are completly right. At first sigh, because it's what happen in the
    software world.

    GPL force "derivative form of work" to be release under GPL. That means
    that if you build a programm that is based under mysql, it must be GPL.
    BUT if you use something "beside" it, it's ok.

    It's what's happen with closed source Nvidia code inside the Linux kernel.
    The driver was first maid for windows not targeting only linux, as for the
    code of one old fiel system. That's a very specific case.

    A more annoying things, is that you mix copyright/source/GPL with real
    things that are not inside the copyright law. So i don't realy know the
    obligation towards the source code when you have the object in your hand.

    In the SW world, if you have a GPL binarie, your provider must provide you
    the source code as said by the GPL. But GPL is a licence on copyrighted
    material which not apply to goods. So i don't know what could happen.
