Wordpress Muti-user can be used in number of ways. Some are using WPMU so that they will be able to manage multiple sites in one installation. Others have it so that they can let users create their own site or blog and since it already supports domain mapping. I have seen one user integrating Classipress with WPMU/Buddy Press plugin tandem for a social networking plugin/classifieds site solution.
You need to get acquainted first on how WPMU works in order to maximize its potential. I suggest to install and play with it. The official wordpress site has tutorials on how to do so.
And for the plugin, I have not yet heard something for that from the developer.
In working and maintaining websites, I believe in one way or another tinkering with codes is necessary.
