WPMU Site-to-site Post Listings

I'm using WPMU to power a network of sites. They all have their own content, but the main blog - #1 in the database - has a large chunk of content that I'd like to use across the other sites.

Is there a way to write a function to get that content and use a regular loop on my other themes and sites on that WPMU installation without getting into RSS stuff?

For example, I have a category (ID 5) on blog #1, and I'd like to display the latest 5 posts from category #5 on blogs 2, 3, 4, etc. in a regular loop so I can access postdata, attachments, and so on. Can that be done?
