A College Online Newspaper Suite as Open Source?

Gurami asks: "I'm a part of a student run team at my school that develops a student website, like those found at many schools, that offers news and services to the college community. Recently, we agreed to create a web based set of apps for a new online student publication. It allows the editors of a publication to manage assignments (articles and media), layout, advertising, workloads, contact information, and some other neat things related to online newspapers/publications, in PHP. Our question is: Is there a market for this sort of web suite, would we be able to package and sell it, or open source it, and sell setup and maintenance services for it to college and university student groups?"
