Is there an existing PHP/MySQL CMS that would be appropriate to manage multiple websites with one backend? The sites will most likely exist on multiple servers and will have different domains. I took a look at wordpress MU, however it doesn't appear to have features for sites on different domains or servers. A CMS that also has an API for publishing would be ideal, as we need to keep track of what content and articles are on what site (I plan on building a Document management system to integrate with the cms). Right now it is looking like I might have to build a custom CMS, but I realllllly don't want to do that as it would require me to reinvent the wheel :-/ Thanks so much guys :)
