Once again, I think you're suffering from a misconception of what a plugin would really do for you as well as what bulletXML really is. It is a format, not a language.
I think you expect a "feed the plugin a bulletXML sheet and it will spit bullet patterns on the screen".
And in that you are wrong. And the stuff you keep linking just displays that.
A plugin would maybe give you specific events and triggers but you still would have to interface those in the event sheet/project objects/behaviors like Newt mentioned in his previous answer.
So it kinda does defeat the purpose of an external plugin anyway. You could not just have a "fits all cases" plugin.
You can try to make me look as the bad guy, but the way you've posted all over this thread blaming internet forums rather than actually trying to understand the answers given don't really stand.
And if you were SO interested in "the common good" you wouldn't be "threatening" of "keeping it to yourself".
Anyway good luck with your project.
