Several coworkers and I have scattered amongst us all sorts of resources related to the mesh stuff we do (RADIUS, networking, RF, antennas, microwave, R&S, Linux, etc), and most of these resources are in the form of PDF or Word docs. Is there a PHP framework that I can easily "yum install" on a CentOS box that would allow us to login and easily share these resources with each other? (Ideally, something like this would have an RSS feed so that we could get updates when a coworker uploads something.)
