My question is this:

Is it possible to have two separate installations of WP with two separate domains sharing the same content?

**Scenario:** User on <http://A.mysite.com> publishes a post. <http://B.mysite.com> uses the exact same database and can show that post as if it was its own.

I've been looking around for quite some time for this solution and cannot find a valid procedure to achieve this.

**My ideas are:**

1. Is there a way to share the database without having the issue of the siteurl and theme stored in the database be an issue.
2. Maybe use just an RSS feed and somehow parse the XML and display them in a template. This is not the best idea because it would have zero functionality that WordPress provides.
3. Find a way to somehow sync the databases but exclude the wp\_options table ?
