If the data isn't dynamic or frequently updated I'd write a script that generates static pages, (from the central database and templates), and push the pages onto their respective sites.

If the data is regularly updated, (hourly, daily, periodically), I'd script it to push new static pages to the "fed sites" periodically.

If most of the content is static and only some of it is dynamic and needs to be fetched in realtime, I'd put the majority of the HTML on the fed sites and use Ajax to pull the dynamic parts of the page.
