Content Distributor?

Hey everybody, I was just wondering if anybody has ever come across anything like this...

I've been looking for something that will distribute articles to a network of blog sites but spin the articles first. Sort of like UAW, but just for my own articles, and my sites would be getting just my own articles. Preferably something that just requires I enter the WP admin and password for each WP install. Anybody think of a way I could do this?

Thanks in advance for any advice!
