Previous commenters have demonstrated a recurrent theme, that the CMS problem is "huge" and "far from solved". But what you must understand is that almost every use case you come across is a niche market. It's a huge number of medium-to-small problems with medium-to-small user sets. A medical school has different needs than a law school and a law firm has different needs yet again, as do hospitals, corporations, the GAO, the White House, etc, etc. One huge value someone could add would be to develop bridges between the user databases. Right now we use Joomla, Wordpress, and MediaWiki. We are fortunate (sort of) in that we have a university's LDAP server to provide user authentication, we just fetch roles out of there, and we really only need logins for the Joomla app. But it would be great if someone could come up with an uber-site authentication system with plugins for the different CMS systems and authentication systems.
