OSS CMS systems can have a great feature set, cost nothing to license and are adaptable, if necessary. What's not to like. Recently we implemented Comatose (a small ruby CMS) into an existing rails site. It didn't need a large number of features but did need some customization to make it work with an already existing, data heavy, application. No problem. From go to whoa it took one person about 3 days, including integrating TinyMCE, existing style templates and changes to accommodate a custom user authentication system. This also included transferring all the existing static pages manually. Most of this would have not been possible had it been closed source.
