Looking for a good enterprise content management system/document management system. The part I am most concerned about is the document management portion. It needs directory/file level permissions assignable by user through a webgui or something equally easy so that management can change permissions. Ideally, this should be FAOSS that can be hosted in the cloud or something with a low monthly cost.
So far I like Alfresco and KnowledgeTree but both look difficult/expensive to host in the cloud. I've also looked at a hosted SVN repo but the permissions setup on that looks pretty complex. Anybody have any suggestions?
