Looking for a way to add new pages and update existing pages across 100 blogs using multi site

A few months ago I asked this question:

We need to manage a few hundred blogs created using WP Multi Site. Right now we need to find a way to update from the mater template any page across site wide. Then we need to be able to add new pages to the master template and have all the sites be updated with the new pages added to each sire . . . site wide again.

the recommendation back then was to use Three WP Broadcast. However I have not been able to get the plugin to add new pages or update existing pages. Barry in the support chat this morning recommended asking the forum. He also said it might need some coding that deals with the pages.

any suggestions would be great.
