Yes, My Project is allready > 1000 lines and even more,.. I have started writing it, each module after another ... I've got allready a lot of experience in other programming languages ( also I have worked as a programmer) But the question is, could communicate a DaliModul, Modbus,.. Etc with the backend db. It's for me a view of top side down, but how could the midlevel comunicate to each oter... "not hirachical" -- http://mail.python.org/mailman/listinfo/python-list
