I have a multisite network installed at http://taxtutor.com. On each of the subdomain sites, I have a "Find Us" post which shows a map to the sites "store" location. On the main site, I have a "Where We Are" post where I wish to show the location of all "stores" in the network.
For the mapping, I use a plugin called "Pazzey's Store Locator" which creates a custom post type and then aggregates all of the custom post types into a map with a single shortcode.
In other words, I can have from one to a gazillion store indicators in a single map, with one indicator for each store locator custom post type post.
With this ability, I feel I can aggregate all the locations into a single map on the main site. Howsomeever ... if I get a lot of sites, or "stores" in the network, it will be a lot of work to keep the map on the main site updated.
So, I would like to find a way to dynamically import the store locator posts from each site, or synchronize the main site with all the sites in the network.
I have tried rss feeds, an autoblog plugin, and have done a lot of web searching trying to find a method.
Is there a way I can achieve the outcome I am striving for?
