 Je zde nejaka vseobecne znama a uznavana open source licence, ktera
 by umoznovala rozsirovani pomoci binary-only modulu a zaroven
 chranila prava autora?

 Ted koukam do FAQ a mozna pokud by bylo stanoveno nejake presne
 definovane API tak by to GLP prezila :-)

        If a program released under the GPL uses plug-ins, what are
        the requirements for the licenses of a plug-in?  

        It depends on how the program invokes its plug-ins. If the
        program uses fork and exec to invoke plug-ins, then the
        plug-ins are separate programs, so the license for the main
        program makes no requirements for them.

        If the program dynamically links plug-ins, and they make
        function calls to each other and share data structures, we
        believe they form a single program, so plug-ins must be
        treated as extensions to the main program. This means they
        must be released under the GPL or a GPL-compatible free
        software license, and that the terms of the GPL must be
        followed when those plug-ins are distributed.

        If the program dynamically links plug-ins, but the
        communication between them is limited to invoking the `main'
        function of the plug-in with some options and waiting for it
        to return, that is a borderline case.
