How to use autoblog on a non-network wordpress install

I am trying to find a plugin that will allow me to share a page across multiple wordpress sites. These sites are NOT in a network. They are installed into separate MySQL databases as separate sites. It is for a company with different divisions and they all need to share one page. I am looking to be able to have a “master” page and that way when I need to make changes I only need to change it on that one page it will change automatically across the other sites. Someone in the livechat suggested this plugin and said that it should work on non-networks but all the instructions seem to be for networks.

Does anyone know if this plugin will work or can someone suggest a better plugin?
