WordPress.org

Syndicate Out syndicates all posts made in a specified category (or optionally all posts) to any other WordPress blog(s) in real time. This enables blog owners to create automatic aggregating, or topic specific blogs from any number of different blog sources without relying on RSS feeds or any kind of timed events.

The plugin uses WordPress' built in XMLRPC functionality to push posts to the target blog. XML-RPC will need to be enabled on the receiving blog in order for this plugin to work. See the installation section for more details.

More information is available, feature requests and bug reports are gladly accepted over on the project's own blog.
