Managing a Private Blogs Network with Wordpress

Hi guys I'm going to create a network of 10 blogs with wordpress (all with different domains and hosted on different servers) I wanted to know if there is a plugin that allow me to manage at all and 10 blogs.

Let me explain, let's say on the home I want to see the last 3 post (for all my blogs), instead of entering the admin of all 10 blogs and going to manually set the command I need a plugin that will allow me to apply the changes to all 10 blogs.

In addition to this should also create a private area for members where they can enter their post.
is there a plugin or more plugins that do all this?

Thanks

PM dp40oz or something like that. He specializes in Blog Networks and he has a plugin called WPNetworker (I think is the name) that does what you're looking for.

BTW, Wordpress blogs aren't "private" blog networks.

Think this is what you are looking for:
