Share exact same content across network with ONE parent.

I installed the template blog plugin and it says it will change the content or its child sites by default and that is exactly what I want.
but is does not seem to do that actually.

Yea I know all about the google and search stuff, this is basically for a wholesale network, INVITE ONLY, so thats not an issue.

I need to controll about 200 domains content from one. Is there such a plugin within the plugins you offer?

Thanks.
