Connecting Posts from Multiple WP Blogs

Hello,

I have multiple WP Blogs. I have a main site that I want to display the most recent posts (snippits) from each of those sites. Possibly in a sidebar.

I have been able to have an automatic display of recent posts with snippits in a sidebar using one of the recent posts plugins, but I cannot figure out how to get it to link to articles from another of my WP sites. I can only make it work for posts from that current site.

Is this something that can be done? I would love a point in the right direction!

Thanks
