Well, I would need to have a full implementation, including implementing objects on the bus in the
scripting language which itself is multithreaded (easy to emply by ooRexx programmers). So this
would mean that a maiinloop integration would be a must.

So there is a need to carry along the gtk+ runtime library on all systems then.

Thank you for your answers and insights!
