Hello,
I am currently developing an internal corporate news site that will be WPMU based, in addition to our current WPMU install. I am also going to be deploying an external WPMU instance.
What I need to do is to be able to push specific posts that are published on the internal new site to the external site based on categories and/or tags (or custom fields). The goal is to have an author publish once on the news portal, and if it should go external add a "external" tag or something similar, so it would automatically be pushed to the external instance.
If this can be done, I want to expand it so I can push posted content to specific customer sites, as well as other external sites, some of which are not running Wordpress.
Note that the external sites can NOT see the internal "parent" server, so it cannot be a data pull, it MUST be a push to the external sites.
Anyone seen anything like this before? Any ideas?
