Multiple Blog “Recent Posts” Plugin?

Alright, I had an idea for the members of my gaming group to have their own blog if they so wanted since I have so many subdomains free.

My plan was to install a fresh WordPress on each of them so they had control over them. Theme, etc.

What I wanted to know though is this:

Is there a way that I can have a widget of sorts on the MAIN site that lists the most recent posts from all these blogs so a visitor from the site can see whats going on in these sub blogs instead of looking through each one themselves.

Also, is it possible to have it so the widget has a link at the bottom for a complete list of the top 50-100 most recent posts. With information such as date, time, and author next to the link. (The link would be the title of the blog post)

As for the actual widget, I would just want the top 10 most recent posts.

Is this possible and if it is not… How can I make it possible? I’d imagine it is if you just call information from the given databases or even different tables prefixes within the same database.

I would probably do a prefix of “NAMEwp_” so I could know which table belongs to which blog.

Any ideas guys? I’d really like to do this because I know for a fact it would be really cool!
