I want one blog on one domain but I just want this blog and domain to be used for admin purposes, so none of the content entered into WP in this area would be published on that domain, rather I was wondering if anyone ever developed a system to then have specific categories of this blog show up in different places ... like on another blog on a different domain.
My first solution would be to stream the feed from the admin blog to a bunch of other WP installs and just publish the content there using something like WP-O-Matic.
But I am wondering whether there is a none RSS-based solution anyone has found?
