I realise this post was quite a while ago.. anyhow this may be of use to someone, even if not to the original poster.
This is an excellent way of ‘syndicating’ content using feeds that contain your article content (atom/rss/xml/someother feed format)
It allows you to have one source that feeds many wordpress sites with content. As soon as you update or add a source article, all the wordpress sites are updated straight away.
Nice huh?
I can assist in setting something like that up.
Heres my company info if you are interested:
